गोविन्द भाष्य (श्रील बलदेव विद्याभूषण - अचिन्त्यभेदाभेद वेदान्त ब्रह्मसूत्र भाष्य सटीक)

departs, the other prāṇas follow."
The prāṇas cannot exist without taking shelter of a maintainer. They take
shelter of the elements of the subtle material body. Therefore it must be accepted
that the subtle material body accompanies the soul. That is the meaning.
Sūtra 4
agny-ādi-gati-śruter iti cen na bhāktatvāt
agni - fire; ādi - beginning; gati - going; śruteḥ - fromthe Śruti-śāstra; iti - thus;
cet - if; na - not;bhāktatvāt - because oif being a metaphor.
If it is said that the Śruti-śāstras describe the departure of fire and other
elements, then I reply: It is not so, because it is a metaphor only.
