Bhṛgu–Bharadvāja-saṃvāda: Vānaprastha-parivrājaka-ācāra, Abhaya-dharma, and Lokānāṃ Vibhāga (Śānti-parva 185)
उदानादुच्छवसिति च प्रतिभेदाच्च भाषते । इत्येते वायव: पज्च चेष्टयन्तीह देहिनम्
bharadvāja uvāca | prāṇena prāṇī calana-phirane kāmaṁ karoti, vyānena vyāyāmaṁ (bala-sādhya udyamaṁ) karoti, apāna-vāyuḥ ūrdhvād adhaḥ gacchati, samāna-vāyuḥ hṛdaye tiṣṭhati, udānena puruṣa ucchvāsaṁ gṛhṇāti ca pratibhedāc ca bhāṣate | ity ete vāyavaḥ pañca ceṣṭayantīha dehinam ||
婆罗多婆阇说道：“凭借普拉那（prāṇa），众生行其寻常动作与作为；凭借遍行气（vyāna），他奋力从事艰苦之业；下行气（apāna）自上而下运行；平衡气（samāna）安住于心域；而凭借上行气（udāna），人得以呼出外息，并因喉、腭等器官之差别而发为言语——成其声与音节。是故此五命风在此运作，使具身者起于行动。”

Educational Q&A
The verse explains that embodied life is animated by five vital airs—prāṇa, vyāna, apāna, samāna, and udāna—each governing specific functions such as movement, exertion, downward flow, inner balancing in the heart-region, and exhalation/speech. Understanding these functions supports self-knowledge and disciplined living.
In the didactic discourse of Śānti Parva, Bharadvāja is instructing about the inner workings of the body and life-force, detailing how the five vāyus operate to produce action and speech in the embodied being.
