Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
यद् यस्माज्जायते भूतं तत्र तत् प्रविलीयते । लीयन्ते प्रतिलोमानि जायन्ते चोत्तरोत्तरम्
yad yasmāj jāyate bhūtaṃ tatra tat pravilīyate | līyante pratilomāni jāyante cottarottaram ||
जो भूत जिस कारण से उत्पन्न होता है, अंततः उसी में लीन हो जाता है। सृष्टि-क्रम में तत्त्व एक-एक करके प्रकट होते हैं और प्रलय में उलटे क्रम से अपने-अपने कारण में विलीन हो जाते हैं।

That effects return to their causes: whatever arises from a source ultimately dissolves back into that source. Creation proceeds step-by-step in a forward sequence, while dissolution happens in the reverse sequence, each entity merging into its causal basis.
Vāyu-deva is explaining a philosophical principle of cosmic process—how beings/elements emerge in an ordered progression and how, at dissolution, they are reabsorbed back into their respective causes—framing a teaching on the nature of existence and impermanence.
