Shloka 6
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 ||
风神说道：“声、触、色、味，以及第五的香——连同领受它们的诸感官作用——在属于因位（微细层面）之意义上是恒常的。因此，即便在坏灭之时，它们也不像粗重之物那样消散。凡无常而粗重者，被称为‘痴迷’，因为它迷惑心识，使人以暂为真。”

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.
