यतोऽशुचिशरीरस्य वायुकोपो महान्भवेत् । वायुकोपात्कुष्ठता च जडत्वादीनुपाश्नुते
yato'śuciśarīrasya vāyukopo mahānbhavet | vāyukopātkuṣṭhatā ca jaḍatvādīnupāśnute
因为身躯不净之人，风气（vāyu，风性之失衡）易大为亢扰；由风气紊乱，便招致如癞病（kuṣṭha）与昏钝迟滞（jāḍya）等诸般疾患。
Lomaharṣaṇa (Sūta) (deduced from Māheśvara-khaṇḍa narrative convention)
Scene: A teacher gestures in caution while a practitioner with an unclean aura is shown suffering imbalance—wind motifs swirling, contrasted with a purified practitioner calm and steady.
