Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
अधिकभ्मूतं तु गन्तव्यं विष्णुस्तत्राधिदेवतम् अब कर्मन्द्रियोंसे सम्बन्ध रखनेवाले विविध विषयोंका निरूपण किया जाता है। तत्त्वदर्शी ब्राह्मण दोनों पैरोंको अध्यात्म कहते हैं और गन्तव्य स्थानको उनके अधिभूत तथा विष्णुको उनके अधिदैवत बतलाते हैं || २४ $ ।।
avāggatir apānaḥ pṛṣṭhaḥ pāyur adhyātmam ucyate
Vāyu said: “The downward-moving course in the body—the apāna vital current—together with the back and the anus, is spoken of as adhyātma, the inner bodily-spiritual basis.” In this teaching, bodily functions are set within a wider frame of meaning, so one understands how inner discipline and right knowledge accord with the cosmic order.
वायुदेव उवाच
The verse identifies specific bodily functions and organs (the downward movement, apāna, the back, and the anus) as ‘adhyātma’—the inner, embodied aspect—within a larger interpretive system that links the individual body to broader metaphysical categories.
Vāyudeva is instructing the listener in a technical, contemplative classification: explaining how elements of the human body and vital energies are to be understood as part of an adhyātma (inner) framework, preparing the ground for correlating them with adhibhūta (outer/elemental) and adhidaiva (divine) correspondences mentioned in the surrounding passage.
