Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
अविशेषाणि चान्यानि कर्मयुक्तानि यानि तु । उभयत्र मनो ज्ञेयं बुद्धिस्तु द्वादशी भवेत्
aviśeṣāṇi cānyāni karmayuktāni yāni tu | ubhayatra mano jñeyaṃ buddhis tu dvādaśī bhavet ||
风神伐由天解释道:“在诸机能之中,尚有其他与行动相系者,其本性并无根本差别。应知心在两域中运作——认知与行动——联结认知诸根与行动诸根;而觉知之智(buddhi)则数为第十二。”
वायुदेव उवाच
The verse teaches a functional classification of the inner and outer faculties: the mind (manas) connects both knowledge and action, while the intellect (buddhi) is counted as the twelfth and serves as the decisive, guiding faculty. Ethical living depends on letting buddhi govern the mind’s engagement with the senses and actions.
Vāyu-deva is instructing the listener in a doctrinal explanation of the faculties (indriyas and inner organs), clarifying how cognition and action are coordinated through the mind and finalized through the intellect.
