In plain words
When the adjuncts are destroyed, the sage abides in Vishnu, who has no adjuncts, with no difference at all, like water in water, space in pure space and fire in fire. Discern this.
Word for word
Discern that with the dissolution of adjuncts the sage abides without distinction in adjunct-free Vishnu, like water in water, space in pure space, and fire in fire.
