एतां विभूतिं योगं च मम यो वेत्ति तत्त्वतः।सोऽविकम्पेन योगेन युज्यते नात्र संशयः॥
etāṃ vibhūtiṃ yogaṃ ca mama yo vetti tattvataḥso ’vikampena yogena yujyate nātra sanśayaḥ
Word by word
The verse says
Whoever truly knows this reach of mine and this power of joining is joined to me by an unshakeable practice. Of this there is no doubt.
In plain words
Avikampena — without trembling. Unshakeable.
The promise is not about intensity. It is about something stopping moving.
And the condition attached is knowledge, specifically — knowing how this works, not feeling strongly about it.
Where you've felt this · in study
A mechanic hears a new noise from an engine and does not look worried. You hear the same noise and your stomach drops. The noise is identical. He is calm because he knows what is making it, and nothing in him has to brace for the possibilities, because he is not running any.
Going deeper
Steadiness is being presented as a by-product of understanding, which runs against how most people think about faith.
The common picture has conviction coming from effort — you believe harder, you hold on tighter, you steady yourself by force. Nothing like that is described here. What is described is somebody who knows how the arrangement works and is therefore not startled by it.
That is an ordinary kind of calm, not a mystical one. Fear in most situations is the mind running possibilities it cannot rule out. Knowledge does not add courage; it removes branches.
So the verse is quietly undercutting a certain anxiety about devotion — the worry that you do not feel enough, often enough, strongly enough. Feeling is not what is being asked for. Understanding is, and understanding has the useful property of staying put when the mood changes.
