Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
अधिकभूतं विसर्गश्न मित्रस्तत्राधिदेवतम् निम्न गतिवाला अपान एवं गुदा अध्यात्म कहा गया है और मलत्याग उसका अधिभूत तथा मित्र उसके अधिदेवता हैं
adhikabhūtaṃ visargaś ca mitras tatrādhidevatam | nimnagativālā apāna evaṃ gudā adhyātma ucyate ca | malatyāgaḥ tad adhikabhūtaṃ mitras tasyādhidevatā ||
Wika ni Vāyu-deva: “Para sa tungkuling ito, ang paglabas na pagtatapon (pagdumi) ang adhibhūta (magaspang at pisikal na aspekto), at si Mitra ang adhidevatā (banal na tagapangasiwa).” Ang hiningang-buhay na dumadaloy pababa ay si Apāna, at ang panloob na luklukan (adhyātma) nito ay sinasabing ang puwit. Kaya ang pag-aalis ng dumi ay pagpapakita sa katawan, samantalang si Mitra ang diyos na nagbabantay sa kaayusang ito.
वायुदेव उवाच
The verse maps a bodily function to a threefold framework: the physical act (adhibhūta), the presiding divine principle (adhidevatā), and the inner seat in the body-mind system (adhyātma). It teaches that even ordinary physiological processes are governed by cosmic order and should be understood with reverence and discipline.
Vāyu-deva is explaining a doctrinal classification of vital functions, identifying Apāna as the downward-moving life-current, locating its adhyātma seat in the guda (anus), and naming Mitra as the adhidevatā connected with the regulation of this eliminative process.
