ऊष्मणा सह विंशो वा संघात: पाउ्चभौतिक: । महान् संधारयत्येतच्छरीरं वायुना सह
Ūṣmaṇā saha viṁśo vā saṅghātaḥ pañcabhautikaḥ | mahān sandhārayaty etac charīraṁ vāyunā saha ||
阿悉多说：“此五大所成之身聚，若并计热力，则可说是二十种原理之合。大原理（mahat）与生命之风（vāyu）共同维持此身。彼风能穿透并遍满全身，然其作用不过是大原理之器具而已。”
असित उवाच
Educational Q&A
The verse frames the body as a composite of elemental principles and explains that the sustaining intelligence-principle (mahat) upholds the body together with vital wind (vāyu); vāyu is presented as an operative instrument rather than the ultimate controller.
In Śānti Parva’s reflective instruction, Asita is describing a philosophical analysis of the body—counting its constituent principles and clarifying how life-functions (vāyu/prāṇa) relate to deeper metaphysical principles (mahat).
