Absence of Self Nature

The Development of the Proof of the Absence of Self-Nature from India to Tibet

Seiji KUMAGAI （JSPS Research Fellow, Kyoto University）

0. Introduction

As Ejima [1980] explains, after Nāgārjuna (ca. 150-250), Mādhyamika thinkers demonstrated the

absence of self-nature in various ways. From the period of Kamalaśīla (ca. 740-795), they had a

tendency to merely gather together traditional arguments. Kamalaśīla enumerated "five" traditional

proofs in his Madhyamakāloka (MĀ). Contrary to Kamalaśīla, Atiśa (982-1054) gave "four" proofs.

According to Kumagai [2007b], Tibetan thinkers generally admitted "five" such acceptable proofs,

basing themselves on Kamalaśīla's MĀ. In my recent study I found that in both Tibetan Buddhism

and in the Bon religion, there was also a tradition which accepted only "four" such proofs.

Here we have a question how they have classified the proofs. In this paper we outline the general

history and characteristics of the classification of acceptable proofs for the absence of self-nature in

Indian Buddhism, Tibetan Buddhism, and Bon religion.

1. Classification of the acceptable proofs for the absence of self-nature in Indian Buddhism

1-1. Those who accept five such proofs

In his Madhyamakāloka (MĀ), Kamalaśīla (ca. 740-795) shows the following "five" acceptable

ways of proving the absence of self-nature in the Mādhyamika school.1

<<Five proofs in the MĀ>>

[Proof 1] That which is absolutely separated from the production from itself, another, and

both, and the production without causes has no self-nature as true. For example, a

1 Moriyama [1991] states that the origin of these five proofs is attested in the 仏性論 composed by 真諦 (Paramārtha, 499-569) so there is a possibility that Kamalaśīla was influenced by 真諦.

sky flower.2

Kamalaśīla calls this proof "four non-obstructive vajra particles" (rdo rje gzegs ma thogs pa med

pa'i bzhi po).

3

[Proof 2] The result, which has already existed, will not be produced again because its

production is non-sense. [The result], which has not existed yet, will not be

produced too, because horns of rabit would also be produced if it were the case.

Later in Tibet it is called "reasoning of vajra particle" (rdo rje gzegs ma'i gtan tshigs,

vajrakaṇahetu*).

4

Kamalaśīla does not give the name of this proof. But later Tibetan thinkers call it "reasoning

which negates production from existence and non-existence" (yod med skye 'gog gi gtan tshigs,

sadasadutpādapratiṣedhahetu*).

[Proof 3] It is not logical that multiple results are produced from one cause. Neither is it

logical that one result is produced from multiple causes… Multiple [results] are

not produced from [multiple] causes… Neither is one [result] produced from [one]

cause.5

Kamalaśīla calls this proof "that which is separated from four extremes of production" (mu bzhi

pa'i skye ba dang bral ba nyid).

6

[Proof 4] Whatever is produced dependently is naturally peaceful.

Later in Tibet it is called "reasoning which negates four extremes

of production" (mu bzhi skye 'gog gi gtan tshigs, catuṣkoṭyutpādapratiṣedhahetu*). 7

Kamalaśīla does not give the name of this proof. But later Tibetan thinkers call it "reasoning of

interdependence" (rten 'brel gyi gtan tshigs, pratītyasamutpādahetu*).

[Proof 5] All things are separated from the self-nature of singularity and multiplicity, so they

have no self-nature.8

Kamalaśīla calls this proof "reasoning which is separated from the self-nature of singularity and

multiplicity" (gcig dang du ma'i rang bzhin dang bral ba'i gtan tshigs).

<<Characteristics of Kamalaśīla's five proofs>>

Kamalaśīla seems to give names to only three of the five, that is proof 1, 3, and 5. In other words

he does not give specific names to all five, nor does he use the term "five great reasons" (gtan tshigs

chen po lnga, pañcamahāhetu*). Thus in the period of Kamalaśīla, there seems to have been only a

vague, unsystematized classification of the proofs.

1-2. Those who accept four proofs

1-2-1. The four proofs of Atiśa (Dīpaṃkaraśrījñāna, ca. 982-1054)

Several different Indian Mādhyamika thinkers gave four proofs for the absence of self-nature.

Among them following Atiśa's presentation seems to be the clearest.10

<<Four proofs of Atiśa>>

[Proof (i)] "reasoning which negates four extremes of production" (mu bzhi skye ba 'gog pa'i

gtan tshigs)

It is not logical that existence is produced again. Neither [is it logical that] non-existence

like a sky flower [is produced]. Both [existence and non-existence] are not produced

because of both errors.11

[Proof (ii)] "reasoning of vajra particle" (rdo rje gzegs ma'i gtan tshigs)

Thing is not produced from itself, another, both [itself and another], nor non-cause. That

is way it has no self-nature essentially.12

[Proof (iii)] "reasoning which is separated from singularity and multiplicity" (gcig dang du

ma dang bral ba'i gtan tshigs)

(proof number 1 of the MĀ)

If all phenomena are analyzed concerning singularity and multiplicity, their self-natures

are not recognized. That is why they are regarded to have no self-nature.13

10 In his BMDP Atiśa gives proper names to all of the four proofs which he had enumarated in his BPP, and he calls them the "four great reasons" (gtan tshigs chen po bzhi, caturmahāhetu*).

(proof

number 5 of the MĀ)

[Proof (iv)] "reasoning of interdependence" (rten cing 'brel par 'byung ba'i gtan tshigs)

[Nāgārjuna] said in the logical reasoning of his Śūnyatāsaptati and

Mūlamadhyamakakālikā, etc.: "Self-natures of things are empty."14

(proof number 4 of

the MĀ)

<<Characteristics of the four proofs of Atiśa>>

Atiśa calls the proof number (i) the "reasoning which negates four extremes of production" (mu

bzhi skye ba 'gog pa'i gtan tshigs). But the content of this proof corresponds to the proof number 2 of

the MĀ, which is called later in Tibet the "reasoning which negates existence and non-existence"

(yod med skye 'gog gi gtan tshigs). On the other hand, Atiśa does not give the proof which

corresponds to the proof number 3 of the MĀ, which is called later in Tibet the "reasoning which

negates four extremes of production" (mu bzhi skye 'gog gi gtan tshigs). That is to say Atiśa gives the

name "mu bzhi skye 'gog gi gtan tshigs" to the proof of the "yod med skye 'gog gi gtan tshigs." We

must also notice that Atiśa's four proofs are different from the four proofs of the MRP as we see later.

1-2-2. Four proofs of the Madhyamakārthasaṃgraha (MAS)15

In the MAS there is an expression: "logic of four reasonings such as negation of four extremes of

production" (mu bzhi skye 'gog la sogs pa'i gtan tshigs bzhi yi rigs pa).16

So there was also a

tradition of four proofs before Atiśa. But it is not sure if the "four proofs" of the MAS are the same or

different from those of Atiśa, because the MAS only names one of them, the reasoning which negates

four extremes of production (mu bzhi skye 'gog gi gtan tshigs).

1-2-3. Four proofs of the Madhyamakaratnapradīpa (MRP)17

The MRP enumerates following four proofs.

[Proof (I)] Thing is not produced from itself, another, both [itself and another], nor

non-cause.18

14 BPP [D 240a7, P 276b7-8]: sTong nyid bdun cu'i rigs pa dang // dBu ma rtsa ba sogs las kyang // dngos po rnams kyi rang bzhin gyi // stong pa nyid ni grub bshad pa //

15 The MAS is regarded to be composed by Bhavya but he seems to be different from Bhāviveka (ca. 500-570) who wrote the Madhyamakahṛdayakālikā. According to Ejima [1980: 33] it was composed by one who existed after Jñānagarbha (ca. 8th cen.) before Atiśa, that is to say between the late of eighth century and the beginning of eleventh century.

16 Ejima [1980: 19], D 329b6-7; P 381a2. 17 The MRP is regarded to be composed by Bhavya but he seems to be different from Bhāviveka (ca.

500-570). According to Yamaguchi [1972: 267], he is one who is after Śāntarakṣita. 18 MRP [P 332b6-332b7]: bdag las mi skye gzhan las min // gnyis las mi skye rgyu med min //


This proof corresponds to the "reasoning of vajra particle" (rdo rje gzegs ma'i gtan tshigs).

[Proof (II)] Multiple things are never produced from one thing, neither is one thing

produced from multiple things. One thing is not produced from one thing too,

neither are multiple things produced from multiple things.19

This proof corresponds to the "reasoning which negates four extremes of production" (mu bzhi

skye 'gog gi gtan tshigs).

[Proof (III)] Existence is not produced, neither is it logical that non-existence produced. Both

existence and non-existence are not produced, neither is produced that which is

not both.20

This proof corresponds to the "reasoning which negates production from existence and

non-existence" (yod med skye 'gog gi gtan tshigs).

[Proof (IV)] It is not logical that thing exists as single, nor is it logical that thing exists as

multiple. How could thing be found other than single or plural?21

This proof corresponds to the "reasoning which is separated from singularity and multipicity"

(gcig dang du bral gyi gtan tshigs).

These four proofs correspond to those of the MĀ, but lack number 4, the "reasoning of

interdependence" (rten 'brel gyi gtan tshigs). These four proofs are therefore different from the four

of Atiśa, who instead omitted the "reasoning which negates four extremes of production" (mu bzhi

skye 'gog gi gtan tshigs).

1-3. Summary

In Indian Mādhyamika, Kamalaīla adopted the position of five proofs of the absence of self-nature.

After Kamalaīla, the tradition of four proofs seems to have become more general than that of five

proofs. However, each thinker did not adopt the same four.

2. Classification of the proofs of the absence of self-nature in Tibetan Buddhism

In Indian Mādhyamika, Kamalaīla gave five proofs, but the position of four proofs seems to have

been more general than that of five proofs. In Tibetan Buddhism there were both positions of four

19 MRP [P 332b7-332b8]: don dam par ni / gcig las du ma'i dngos mi skye // du mas gcig gi dngos mi skye // gcig las gcig (P. cig) kyang mi skye zhing // du ma las kyang du ma min //

and five proofs in the beginning of phyi dar. However, the position of five proofs seems to have

become more general through time.22

Type (A)

In later periods the five proofs were further classified into

three types as follows:

gcig dang du bral, rten 'brel

rdo rje gzegs ma, yod med skye 'gog, mu bzhi skye 'gog

Type (B)

rten 'brel

gcig dang du bral, rdo rje gzegs ma, yod med skye 'gog, mu bzhi skye 'gog

Type (C): synthesis of Type (A) and Type (B)

rten 'brel (first)

gcig dang du bral (second)

rdo rje gzegs ma, yod med skye 'gog, mu bzhi skye 'gog (third)

2-1-1. Classification of Gro lung pa Blo gros 'byung gnas (ca. 1100, bKa' gdams pa)

In his Lam rim rnam bshad Gro lung pa gives "five great reasons" (gtan tshigs chen po lnga)

according to Kamalaīla.23 Gro lung pa classifies the five proofs in two ways as follows:24

- Classification of Gro lung pa (a): Type (A)

gcig dang du bral, rten 'brel: proof analyzing from the point of view of the self-nature of

things

rdo rje gzegs ma, yod med skye 'gog, mu bzhi skye 'gog: proof analyzing from the point of

view of causes and results.

- Classification of Gro lung pa (b): Type (B)

rten 'brel: proof which is the "recognition of pervasion by contradiction" ('gal bas khyab pa

2-1-2. Classification of Tsong kha pa Blo bzang grags pa (1357-1419, dGe lugs pa)

Tsong kha pa also classifies five proofs in two ways in his Legs bshad snying po and Legs bshad

gser phreng as follows:

- Classification of the Legs bshad snying po:25

rten 'brel

Type (B)


- Classification of the Legs bshad gser phreng:26

gcig dang du bral etc.: proof which examines self-nature

Type (A)

rdo rje gzegs ma, mu bzhi skye 'gog, etc.: that which examines causes and results

In the latter classification, proofs included in "etc." seem to be rten 'brel and yod med skye 'gog,

which are stated in Legs bshad snying po.

2-1-3. Classification of Rong ston Shes bya kun rig (1367-1449, Sa skya pa)27

In his Rigs lam kun gsal Rong ston synthesizes two classifications (Type A and B), he finally

shows the classification into three (Type C) as follows:28

- Classification of the Rigs lam kun gsal (a): Type (A)

gcig dang du bral, [rten 'brel]: that which decides completely the meaning of emptiness

rdo rje gzegs ma, yod med skye 'gog, mu bzhi skye 'gog: that which does not decide

completely the structure of middle way

- Classification of the Rigs lam kun gsal (b): Type (B)

rten 'brel: that which gets rid of both exaggeration of existence and exaggerated denial of

non-existence.

25 Legs bshad snying po [P 140b6-7]: dBu ma snang ba las ni rdo rje gzegs (P gzigs) ma dang yod med skye 'gog dang mu bzhi skye 'gog dang gcig dang du bral yang gsungs la / rten 'brel gyi gtan tshigs kyang gsungs te de ni 'gal zla dmigs pa'i rtags so //

gcig dang du bral, rdo rje gzegs ma, yod med skye 'gog, mu bzhi skye 'gog: that which gets

rid of the exaggeration of existence but does not get rid of exaggerated denial of

non-existence.

- Classification of the Rigs lam kun gsal (c): Type (C) which is synthesis of Type (A) and (B)

rten 'brel (first)



In the period of Rong ston, the synthesis of the various classifications caused the new

classification of proofs of the absence of self-nature to become more complex.

2-1-4. Classification of lCang skya Rol pa'i rdo rje (1717-1786)

In his lCang skya grub mtha' lCang skya explains five proofs according to different Mādhyamika

schools as follows.

[A] Sautrāntikamādhyamika focus the "reasoning which negates the four extremes of production"

(mu bzhi skye 'gog gi gtan tshigs) among five proofs, as seen in Jñānagarbha's Satyadvayavibhaṅga

(SDV).29

[B] Among Yogācāramādhyamika thinkers, Kamalaśīla gives five proofs, rdo rje gzegs ma, yod

med skye 'gog, mu bzhi skye 'gog, gcig du bral, and rten 'brel gyi gtan tshigs.

30 Śāntarakṣita focuses

on the "logic which is separated from singularity and multiplicity" (gcig du bral gyi rigs pa).31

[C] For Prāsaṅgikamādhyamika thinkers, the rdo rje gzegs ma,

32 yod med skye 'gog,33 and mu

phenomena (gang zag dang chos kyi bdag med). Then, the rten 'grel is the king of logic (rgyal po'i

rten 'brel (first)

Thus, according to lCang skya, Prāsaṅgikamādhyamika give the classification of Type

(C) as follows:



2-2. Position which accepts four traditional proofs

2-2-1. Four proofs of Rong zom Chos kyi bzang po (beginning of 11th cen.)

<<Rong zom's four proofs>>

In his Grub mtha'i brjed byang, Rong zom Chos kyi bzang po gives four great reasonings as

follows:38

[1] "[reasoning] of four daggers of middle way" (dbu ma'i phur bzhi):

39

[2] "[reasoning] which is separated from singularity and multiplicity" (gcig dang du ma dang bral

non-production from

We can enumerate following characteristics of Rong zom's four proofs.

- Rong zom has a position of four proofs without the "reasoning which negates the production from

existence and non-existence" (yod med skye 'gog gi gtan tshigs).

- Atiśa gives substantially the four proofs without the "reasoning which negates four extremes of

production" (mu bzhi skye 'gog gi gtan tshigs), so Atiśa's four proofs are different from Rong

zom's.

- Rong zom also uses a special name: "[reasoning] of four daggers of middle way" (dbu ma'i phur

bzhi) for the proof of the "reasoning of vajra particle " (rdo rje gzegs ma'i gtan tshigs)

<<Relationship with Bonpo's four proofs>>

Bonpo thinkers give four proofs without mu bzhi skye 'gog like Atiśa, so their four proofs are

different from Rong zom's.

2-2-2. Two positions of four and five proofs referred in the gZhung lugs legs bshad

(anonymous: from the 2nd half of 13th century to the 1st half of 14th century43

)

As we see later, the gZhung lugs legs bshad said there were two traditions of four proofs and five

proofs in Mādhyamika school, and this treatise itself seems to adopt the position of five proofs.44

Five proofs in the gZhung lugs legs bshad are as follows:

But it is not sure to which proofs the four reasonings correspond in this case.

[1] gcig dang du bral gyi gtan tshigs:45

[2] rdo rje gzegs ma'i gtan tshigs:

that which negates by examining self-nature of things. 46

43 The gZhung lugs legs bshad had been regarded to be composed by Sa skya paṇḍita Kun dga' rgyal mtshan (1182-1251). However, as stated by Jackson [1985], this is not a treatise written by Sa skya paṇḍita.

that which negates by examining causes.

Concerning its date, Jackson [1985] states the gZhung lugs legs bshad is a work in the sixteenth century or before. However, as I wrote in another paper (Kumagai [forthcoming]), it seems to date from the 2nd half of 13th century to the 1st half of 14th century.

2-3. Summary

[1] In Tibetan Buddhism the position of "five proofs" according to Kamalaśīla's MĀ seems to be

general.

[2] However, in early period of phyi dar, there was also a position of "four proofs" such as Rong

zom (beginning of 11th cen.). But Rong zom's four proofs are different from Atiśa's.

[3] Unlikely to Indian Buddhists, Tibetan Buddhist thinkers classify "five proofs" in two ways.

- Type (A)



- Type (B)

rten 'brel


[4] In the period of Rong ston (1367-1449), Tibetan Buddhist synthesized the classifications of Type

(A) and (B).

- Type (C)

rten 'brel (first)

[5] lCang skya (1717-1786) gave the classification of five proofs according to different schools such

as Sautrāntikamādhyamika, Yogācāramādhyamika, and Prāsaṅgikamādhyamika.

[6] These detailed classifications are not attested in Indian Mādhyamika treatises, so it seems to be

difficult to apply them directly to the understanding of Indian Mādhyamika treatises.

3. Classification of proofs of the absence of self-nature in the Bon religion

3-1. Four proofs in the Theg rim (rediscovered in the fifth Rab-byung, i.e. 1267-132650

)

The Theg rim refers "four types of proof of great reason" (gtan tshigs chen po'i sbyor ba rnam pa

bzhi). 51

However, it is not sure which the four proofs are. (Its commentary, the Theg 'grel

enumerates each name of the four proofs.)

3-2. Four proofs in the Theg 'grel (rediscovered in the fifth Rab-byung, i.e. 1267-132652

)

The Theg 'grel refers the "six great reasons" (gtan tshig chen po drug). However it gives, in fact,

only the following four: "[reasoning of] great peg of svastika" (g-yung drung gzer chen), "[reasoning

of] great interdependence" (rten 'brel chen po), "[reasoning] which is separated from singularity and

multiplicity" (gcig dang du bral), "[reasoning which] negates production from existence and

non-existence" (yod med skye ba dgag pa).53

The Theg 'grel does not explain the content of each proof, so it is not sure if the "[reasoning of]

great peg of svastika" (g-yung drung gzer chen) indicates the reasoning of vajra particle (rdo rje

gzegs ma'i gtan tshigs) or the reasoning which negates four extremes of production (mu bzhi skye

'gog gi gtan tshigs).

In any case the Theg 'grel's four reasons are different from Rong zom's four reasons which lack

the "reasoning which negates production from existence and non-existence" (yod med skye 'gog gi

gtan tshigs).

50 Karmay [1972: 152n2]. 51 Theg rim [375.3-5]: Thugs rje chen po sems dpa'i theg pa ni // gtan tshigs chen po'i sbyor ba

rnam pa bzhis // We must notice that the Thugs rje chen po sems dpa'i theg pa corresponds to Buddhist Yogācāra

school. (See Mimaki [1994: 130, 132]). 52 Karmay [1972: 152n2]. 53 Theg 'grel [450.6-451.2]: gtan tshigs chen po drug gis 'gegs pa ste / spros pa'i rgyu la gnod pa

3-3. Four proofs of mNyam med Shes rab rgyal mtshan (1356-1415)

In his Sa lam rang 'grel, mNyam med classifies four proofs as follows:54

gcig dang du bral gyi rtags

This is the classification

Type (B).

yang dag par 'brel yul 'gog pa g-yung drung gzer chen gyi rtags

yod med skye 'gog gi rtags

tha snyad du 'gal zlar bsgrub pa rten 'brel chen po'i gtan tshig

The "reasoning of great peg of svastika" (g-yung drung gzer chen gyi rtags): non-production from

itself, another, both itself and another, and without causes.55

This reasoning corresponds to the

"reasoning of vajra particle" (rdo rje gzegs ma'i gtan tshigs). That is way mNyam med admits four

proofs, omitting the reasoning which negates production from existence and non-existence (yod med

skye 'gog gi gtan tshigs). His four proofs are the same with Atiśa's, but different from Rong zom's.

3-4. Summary

In Indian and Tibetan Buddhism, both four and five proof systems were accepted. However, in the

Bon tradition, only the position which accepts four proofs is so far attested. Buddhist "reasoning of

vajra particle" (rdo rje gzegs ma'i gtan tshigs) is called the "reasoning of great peg of svastika"

(g-yung drung gzer chen gi rtags) in the Bon tradition. Four proofs of the Theg 'grel and mNyam

med correspond to the Indian Buddhist Atiśa's, but different from the Tibetan Buddhist Rong zom's.

mNyam med separates the "reasoning of interdependence" (rten 'brel gi gtan tshigs) from the other

proofs, that is the classification Type (B). Thus, Bonpo thinkers created their own classifications of

proofs of the absence of self-nature, by adopting parts of various classifications of Indian and

Tibetan Buddhist thinkers.

4. Conclusions

Now we summarize characteristics of the classification of proofs of the absence of self-nature in

Indian Buddhism, Tibetan Buddhism, and Bon religion, which are examined in this paper.

[1] Indian Mādhyamika

- There are both positions of five proofs such as Kamalaśīla and four proofs such as Atiśa.

- The tradition of four proofs seems to be more general than that of five proofs.

- Each thinker adopts different four proofs.

We can therefore say that Indian Mādhyamika thinkers enumerated representative proofs but they

did not classify them in detail.

[2] Tibetan Buddhism

- There existed both four and five proofs at the beginning of phyi dar, but the position of five proofs

seem to be more general.

- The four proofs of Tibetan Buddhism are different from those of Indian Buddhism.

- Fundamentally there are following two types of basic classification in Tibetan Buddhism:

- Type (A)



- Type (B)

rten 'brel


- In the period of Rong ston (1367-1449), Tibetan Buddhist synthesized the classifications of Type

(A) and (B).

- Type (C)

rten 'brel (first)



- lCang skya (1717-1786) gave the classification of five proofs according to schools such as

Sautrāntikamādhyamika, Yogācāramādhyamika, and Prāsaṅgikamādhyamika.

Thus, Tibetan Buddhist thinkers seem to have classified proofs in detail, so the classification

became more complex.


[3] Bonpo

- In the Bon tradition, only the position of four proofs is so far attested.

- Bonpos' four proofs correspond to Atiśa's but they are different from Rong zom's.

- mNyam med separates the reasoning of interdependence (rten 'brel gi gtan tshigs) from the other

proofs. (Type B)

Bonpo thinkers thus seem to have created their own theories, by adopting partially various

classifications of Indian and Tibetan Buddhist thinkers.
