Shloka 4
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 ||
风神（Vāyu-deva）说道：“凡由某一根源而生之有情，终必还归于彼根源。诸元素依创造之顺序次第显现；而在逆序之中，又各各融入其自因。”
वायुदेव उवाच

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.
