Nārada–Devamata Dialogue on Prāṇa, Apāna, and Udāna
शुक्राच्छोणितसंसृष्टात् पूर्व प्राण: प्रवर्तते । प्राणेन विकृते शुक्रे ततो5पान: प्रवर्तते,रजमें मिले हुए वीर्यसे पहले प्राण आकर उसमें कार्य आरम्भ करता है। उस प्राणसे वीर्यमें विकार उत्पन्न होनेपर फिर अपानकी प्रवृत्ति होती है
śukrāc choṇita-saṃsṛṣṭāt pūrvaṃ prāṇaḥ pravartate | prāṇena vikṛte śukre tato 'pānaḥ pravartate ||
Nārada explained: “When semen (śukra) becomes mixed with blood (śoṇita), first the vital breath prāṇa begins its operation there. When that semen is transformed by prāṇa, then apāna, the downward-moving life-force, subsequently becomes active.”
नारद उवाच
Life and generation proceed through an ordered activation of vital forces: prāṇa initiates activity in the mixed generative substances, and after prāṇa brings transformation, apāna begins its function—suggesting that embodied life is structured, purposeful, and worthy of ethical regard.
Nārada is describing a step-by-step account of how conception and bodily formation begin, focusing on the sequential roles of prāṇa and apāna once semen is mixed with blood.
