Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
शब्द: स्पर्शस्तथा रूप॑ रसो गन्धक्षु पञजचम: । क्रिया: करणनित्या: स्युरनित्या मोहसंज्ञिता:
śabdaḥ sparśas tathā rūpaṃ raso gandhaś ca pañcamaḥ | kriyāḥ karaṇa-nityāḥ syur anityā moha-saṃjñitāḥ ||
風神ヴァーユは語った。「音・触・色・味、そして第五の香—それらを捉える感官のはたらきとともに—は、因の位（微細の次元）に属するがゆえに恒常である。ゆえに壊滅の時にあっても、粗大なもののように消え失せはしない。無常で粗大なものは『モーハ（迷妄）』と呼ばれる。移ろうものを真実と取り違えさせ、心を欺くからである。」
वायुदेव उवाच
Educational Q&A
The verse distinguishes the subtle, causal-level constituents (sense-objects and the sensory functions as rooted in subtle mind/causes) from gross, perishable manifestations. What is transient is labeled “moha” because attachment to it produces delusion; discernment of nitya vs. anitya supports detachment and clarity.
Vāyu-deva is instructing the listener in a philosophical register, explaining how perception works through the five sense-objects and their operations, and why gross impermanent things dissolve while subtler causal principles are treated as enduring in the context of pralaya.
