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 ||
ビーシュマは言った。「月をはじめとする諸々の光明の昇りを常に起こし、また有身の者の内にあって賢者たちが生命の流れ『ウダーナ』(Udāna)と呼ぶもの——その力こそ、上昇の運行を司る宇宙の風として示され、内なる息吹と外なる天の秩序とを結び合わせるのである。」
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.
