The Bhāgavata Purāṇa relates the following story regarding Saṁdīpanī Muni: While staying as students at the residence of Sandīpanī Muni, the two brothers—Śrī Kṛṣṇa and Balarāma— and their friend, Sudama (Su-dāma), mastered every single lesson, although only having been instructed in each once. Upon the rapid completion of their studies, they persuaded their teacher to ask for the preceptor's dakṣiṇa (his fee for providing instruction) of his own choosing. Saṁdīpanī asked for the restoration of his child, who had disappeared in the ocean at Prabhāsa (on the Western Coast Gujarat state of India, close to Somnath temple). The two brothers traveled to Prabhāsa and found that the son had been snatched away by a being named Śaṅkhāsura (literally, conch demon; In the Mahābhārata, Śaṅkha is mentioned as one of Kubera's treasures, as well as the being presiding over it).
