Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
अन्तरात्मनि चाप्येते नियता: पठच वायव: । वाड्मनोबुद्धिभि: सार्द्धमिदमष्टात्मके जगत्
antarātmani cāpy ete niyatāḥ pañca vāyavaḥ | vāṅmanobuddhibhiḥ sārdham idam aṣṭātmake jagat ||
风神伐由说道：“在内我之中（寄居于身的有情），有五种生命之风依律而住：普拉那（prāṇa）、阿帕那（apāna）、乌达那（udāna）、萨玛那（samāna）与维亚那（vyāna）。因其局限于身内，故极其微细。若再与言语、心与智（理智）合计，则成八数。此八者，乃此世界生成之根本物质基底。”
वायुदेव उवाच
Educational Q&A
The verse teaches an eightfold framework of embodied existence: five vital airs (prāṇa, apāna, udāna, samāna, vyāna) together with speech, mind, and intellect. These are presented as subtle inner constituents and as the material basis (upādāna) through which the world of experience is constituted.
Vāyu-deva is instructing the listener in an inner, yogic-cosmological analysis of the person. He identifies the regulated vital functions within the body and then expands the count by adding the cognitive and expressive faculties, framing them as foundational principles that underlie worldly manifestation and experience.
