उपाधिविलयाद्विष्णौ निर्विशेषं विशेन्मुनिः ।जले जलं वियद्व्योम्नि तेजस्तेजसि वा यथा ॥ ५३ ॥
In plain words
When the limiting adjuncts dissolve, the sage enters the all-pervading Viṣṇu with no difference left over — the way water goes into water, space into space, light into light.
Close to the Sanskrit
From the dissolution of the limiting adjuncts, the sage enters into Viṣṇu, the all-pervading, without any distinction — as water into water, space into space, or light into light.
