अग्नीषोमोत्पत्तिः
Agni–Soma Origin and the Brahmāgnīṣomīya Doctrine
उदयं ज्योतिषां शश्वत् सोमादीनां करोति यः । अन्तर्देहेषु चोदानं यं वदन्ति मनीषिण:
udayaṁ jyotiṣāṁ śaśvat somādīnāṁ karoti yaḥ | antardeheṣu codānaṁ yaṁ vadanti manīṣiṇaḥ ||
भीष्म म्हणाले—जो सोमादी ज्योतींचा उदय सदैव घडवितो आणि ज्याला ज्ञानी पुरुष देहांतर्गत ‘उदान’ नामक प्राणप्रवाह म्हणतात, तोच ऊर्ध्वगतीचा अधिपती असा महान् वायू होय; अंतःप्राण व बाह्य आकाशीय व्यवस्था यांचा संबंध दर्शविणारी ती शक्ती आहे.
भीष्म उवाच
The verse links macrocosm and microcosm: the same governing principle that orders the rising of celestial lights is present within living beings as Udāna, the upward-moving vital force. It suggests an ethical-spiritual vision where understanding inner discipline (prāṇa) aligns one with cosmic order (ṛta/dharma).
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on higher knowledge and the foundations of order. Here he identifies a cosmic function—causing the luminaries to rise—and equates it with the internal life-current called Udāna, presenting a contemplative teaching on how universal forces operate within the body.
