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 ||
Bhīṣma dit : Celui qui, sans cesse, fait se lever les luminaires—à commencer par la Lune—et que les sages, au sein des êtres incarnés, nomment le courant vital appelé Udāna : cette puissance est désignée comme le vent cosmique qui gouverne l’élan vers le haut, reliant le souffle intérieur à l’ordre des cieux au-dehors.
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.
