Verse 25

आत्मेच्छयैव घनतां समुपागतान्त-रात्मेच्छयैव तनुतामुपयाति काले ।संसारजालरचनेयमनन्तमाया-ज्वालेह वातवलयादिव पावकस्य

In plain words

Having come to thickness by the very will of the ātman, by the very will of the inner ātman it goes, in time, to thinness: this weaving of the net that is saṃsāra -- a flame of unending māyā -- does so here as the flame of a fire does from a whirl of wind.
