वस्तिमूलं गुदं चैव पावकं समुपाश्रितः । वहन्मूत्रं पुरीषं वाप्यपानः परिवर्तते ॥ १०२ ॥
vastimūlaṃ gudaṃ caiva pāvakaṃ samupāśritaḥ | vahanmūtraṃ purīṣaṃ vāpyapānaḥ parivartate || 102 ||
वस्तिमूळ, गुदा आणि पाचक अग्नीच्या जवळ आश्रय घेऊन अपान-वायू मूत्र व पुरीष बाहेर नेण्याचे कार्य करतो॥
Sanatkumara (teaching Narada the functions of the prāṇas)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bibhatsa
It defines Apāna’s downward-moving role—elimination and cleansing—showing that bodily purification is a prerequisite support for steadiness in yoga and Moksha-dharma practice.
While not directly praising bhakti, it supports devotional discipline by emphasizing purity and bodily order; a stable, purified system helps sustained japa, vrata, and focused remembrance of Vishnu.
It reflects applied yogic/Āyurvedic physiology (vāyu functions and digestive fire). It is not a direct Vedāṅga lesson like Vyākaraṇa or Jyotiṣa, but it is technical body-knowledge used in sādhanā.
