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 ||
见那仙人具足一切资粮——由圣闻而成的学识与严整的行持——迦叶这“焚敌者”便依礼趋近。以由衷的敬信与师道之行而侍奉,遂令那成就的大士心生欢喜。
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.
