Kṛṣṇa Comforts His Parents, Restores Ugrasena, Studies with Sāndīpani, and Returns the Guru’s Son
सर्वं नरवरश्रेष्ठौ सर्वविद्याप्रवर्तकौ । सकृन्निगदमात्रेण तौ सञ्जगृहतुर्नृप ॥ ३५ ॥ अहोरात्रैश्चतु:षष्ट्या संयत्तौ तावती: कला: । गुरुदक्षिणयाचार्यं छन्दयामासतुर्नृप ॥ ३६ ॥
sarvaṁ nara-vara-śreṣṭhau sarva-vidyā-pravartakau sakṛn nigada-mātreṇa tau sañjagṛhatur nṛpa
Oh Rey, Kṛṣṇa y Balarāma, los mejores entre los hombres y promulgadores originales de todo saber, asimilaban al instante cada materia con oírla una sola vez. Así, con concentración firme, aprendieron las sesenta y cuatro artes en sesenta y cuatro días y noches, y luego complacieron a su maestro ofreciéndole la guru-dakṣiṇā.
The following list comprises the sixty-four subjects mastered by Lord Kṛṣṇa and Lord Balarāma in sixty-four days. Additional information may be found in Śrīla Prabhupāda’s Kṛṣṇa, the Supreme Personality of Godhead.
In Canto 10, Chapter 45, Śukadeva explains that Kṛṣṇa and Balarāma mastered all disciplines simply by hearing them once, showing their divine completeness even while performing human-like pastimes.
They enacted the ideal conduct (maryādā) for society—honoring the guru and the discipline of learning—so people would value education, humility, and guru-sevā.
Approach learning with humility, attentive hearing (śravaṇa), and respect for teachers; spiritual growth also depends on focused listening and sincere service.
