Abhaya-Itihāsa: Karma, Indriyas, and the Non-sensory Brahman
Brāhmaṇī–Brāhmaṇa Saṃvāda
तत एव प्रवर्तन्ते तदेव प्रविशन्ति च | “उसीसे सृष्टि आदिका विस्तार होता है और उसीमें उसकी स्थिति है। प्राण, अपान, समान, व्यान और उदान--से उसीसे प्रकट होते और फिर उसीमें प्रविष्ट हो जाते हैं ।।
tata eva pravartante tadeva praviśanti ca |
风神伐由曰：唯由彼而起，亦唯归彼而入。诸生命作用——普拉那、阿帕那、萨玛那、维亚那与乌达那——皆从那至上根基显现，终复融归其中。

Educational Q&A
All vital forces and life-functions originate from a single supreme ground (tad) and finally return to it. The verse emphasizes unity behind the many operations of life, encouraging detachment and insight into the source that sustains all activity.
Vāyu-deva is explaining the nature of the vital airs: they emerge from an ultimate principle, function within embodied life, and then dissolve back into that same principle. This instruction frames physiology as a spiritual teaching about origin, dependence, and dissolution.
