यथाग्निरुद्धतशिखः कक्षं दहति सानिलः ।तथा चित्तस्थितो विष्णुर्योगिनां सर्वकिल्बिषम् ॥
In plain words
Just as a roaring fire whipped by the wind burns through dry brush, so Viṣṇu, abiding within the minds of yogīs, burns away all their impurities.
Close to the Sanskrit
Just as fire with raised flames along with wind burns dry grass, so Viṣṇu situated in the mind [burns] all the blemish of yogīs.
