Bhagavad Gita, Chapter 15, Verse 3-4

Its form is not here perceived as such, neither its end, nor its origin, nor its existence. Having cut asunder this firm-rooted Ashvattha with the strong axe of non-attachment, then that Goal is to be sought for, going whither they the wise do not return again. I seek refuge in that Primeval Purusha whence streamed forth the Eternal Activity.

Even something as vast as this tree is described here as genuinely hard to see clearly, no visible beginning or end, and what's called for in response is a real, decisive action, cutting it down, not just admiring it.

Krishna doesn't pretend this structure is easy to grasp, its true shape is named as hidden from ordinary sight, before naming detachment as an actual tool, an axe, used to sever something that's been growing a long time. Real effort is required here, not passive observation.
