Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
प्रजन: सर्वभूतानामुपस्थो<ध्यात्ममुच्यते
prajanaḥ sarvabhūtānām upastho 'dhyātmam ucyate
قال فايُو: «إن القدرة المُولِّدة التي بها تُنجب جميع الكائنات تُسمّى أُپَسْثَ (upastha)، أي عضو التناسل؛ وفي التحليل الباطني تُذكر على أنها مبدأ من مبادئ الأدهْياتما (adhyātma).»
वायुदेव उवाच
The verse identifies procreation as a specific inner principle: the reproductive faculty (upastha) is not merely anatomical but is categorized within adhyātma analysis as a fundamental power responsible for the continuation of life among all beings.
Vāyudeva is explaining an adhyātma-oriented classification of bodily functions and inner principles, defining ‘upastha’ in terms of its universal role in generation (prajana) for all creatures.
