Arjuna’s request to Krishna and the opening of the Kāśyapa–Brāhmaṇa mokṣa discourse (Āśvamedhika-parva 16)
उपपन्नं च तत्सव॑॑ श्रुतचारित्रसंयुतम् । भावेनातोषयच्चैनं गुरुवृत्त्या परंतप:
upapannaṃ ca tat sarvaṃ śrutacāritrasaṃyutam | bhāvenātoṣayac cainaṃ guruvṛttyā paraṃtapaḥ ||
तो मुनि श्रुतीने संपन्न व सच्चरित्राने युक्त—सर्वथा उपपन्न होता. परंतप काश्यपाने गुरुवृत्तीने व अंतःकरणातील भावाने सेवा करून त्यांना प्रसन्न केले.
ब्राह्मण उवाच
Spiritual worth is measured by learning joined to upright conduct, and a disciple progresses through sincere inner devotion (bhāva) expressed as respectful service and proper teacher-oriented conduct (guru-vṛtti).
Kāśyapa encounters an accomplished sage, recognizes his qualifications (learning and character), accepts him as a guru, serves him with devotion, and thereby satisfies the sage.
