Sutra

An user story is like a "sutra" - an aphorism, that needs to be delved into
detail to understand its entirety.
And this is needed if you want to test well.

The Details of “How-To”BIG Picture & Goal Setting

... the act of breaking the "big" into "small" (user stories) makes one forget about who the end user is and what they value.
Hence it is necessary to think from the end user's perspective as what they do and how the user story fits in the end user flow and how non-functional attributes of the larger flow matter to the user story.
