Vivāha-dharma: Kanyā-pradāna, Śulka, and Pāṇigrahaṇa-niṣṭhā (अनुशासन पर्व, अध्याय ४४)
स्थितिं च धर्मे जग्राह स तस्माद् गुरुवत्सल: । अनुज्ञातश्न गुरुणा चचारानुत्तमं तप:
sthitiṁ ca dharme jagrāha sa tasmād guruvatsalaḥ | anujñātaś ca guruṇā cacārānuttamaṁ tapaḥ ||
Bhishma said: Therefore, being devoted to his teacher, he sought and secured steadfastness in dharma. Then, having received his teacher’s permission, he undertook the highest austerity—so that his commitment to righteousness would remain unbroken.
भीष्म उवाच
True dharma is sustained by disciplined practice (tapas) guided by humility and respect for one’s teacher; ethical steadiness is something to be consciously sought and maintained.
A devoted disciple asks for unwavering establishment in dharma, receives the guru’s permission, and then begins an intense course of austerity to secure that moral and spiritual stability.
