Shloka 25
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
ヴァーユは言った。「身体における下向きの運行—アパーナ（apāna）という生命の気流—に、背と肛門を合わせたものは、アディヤートマ（adhyātma）、すなわち身と霊の内なる基盤と説かれる。」この教えでは、身体の働きをより大きな意味の枠組みに配し、内なる修練と正しい知が宇宙の秩序といかに結びつくかを悟らせる。

Educational Q&A
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.
