Vāc–Manas Saṃvāda: Prāṇa-Apāna and the Primacy Debate (वाक्–मनस् संवादः)
ततो वाचस्पतिर्जज्ञे त॑ं मन: पर्यवेक्षते । रूपं भवति वैवर्ण समनुद्रवते मन:,उससे वाचस्पति (वेदवाणी)-का प्राकट्य होता है। उसे मन देखता है। मनके अनन्तर रूपका प्रादुर्भाव होता है, जो नील-पीत आदि वर्णोंसे रहित होता है। वह रूप मनकी ओर दौड़ता है
tato vācaspatiḥ jajñe taṁ manaḥ paryavekṣate | rūpaṁ bhavati vaivarṇaṁ samanudravate manaḥ ||
Then Vācaspati—the lord of speech, the Vedic utterance—comes into manifestation. The mind beholds it attentively. After the mind, form itself arises—form that is without the differentiations of color such as blue or yellow. That form then hastens toward the mind.
ब्राह्मण उवाच
The verse presents a hierarchy of manifestation: speech (vāc) arises, the mind apprehends it, and then form arises and moves under the mind’s orientation. Ethically, it implies that disciplined mind governs expression and the shapes that actions and perceptions take.
A Brahmin speaker describes a subtle process of origination: Vācaspati manifests, the mind observes it, then a colorless form appears and hastens toward the mind—depicting how inner faculties precede and guide outward manifestation.
