Arjuna’s request to Krishna and the opening of the Kāśyapa–Brāhmaṇa mokṣa discourse (Āśvamedhika-parva 16)
विस्मितश्ाद्भुतं दृष्टवा काश्यपस्तद् द्विजोत्तमम् । परिचारेण महता गुरुं त॑ पर्यतोषयत्
vismitaś cādbhutaṁ dṛṣṭvā kāśyapas tad dvijottamam | paricāreṇa mahatā guruṁ taṁ paryatoṣayat ||
迦叶见那二生中最胜者,奇妙非常,心中惊叹不已。遂奉之为师,以至诚勤谨而侍奉,因其殷勤供事,终于使导师大为欢喜。
ब्राह्मण उवाच
The verse teaches that genuine spiritual and ethical learning is grounded in humility and reverent service: recognizing excellence (dvijottama), accepting rightful guidance (guru), and pleasing the teacher through sincere attendance (paricaryā) rather than mere display of knowledge.
Kāśyapa encounters an extraordinary and eminent brāhmaṇa, is struck with wonder, accepts him as his guru, and through sustained, devoted service succeeds in satisfying him—setting the stage for instruction or spiritual benefit that follows from proper discipleship.
