Lord Kṛṣṇa is not properly understood even by such exalted personalities as Lord Śiva and Lord Brahmā, what to speak of ordinary men, but by His causeless mercy He bestows the benediction of devotion upon His devotees, who can thus understand Kṛṣṇa as He is. Bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). No one within this universe can understand Kṛṣṇa in truth, but if one engages in devotional service one can understand Him perfectly well. This is also confirmed by the Lord in the Seventh Chapter of Bhagavad-gītā (BG 7.1):
- mayy āsakta-manāḥ pārtha
- yogaṁ yuñjan mad-āśrayaḥ
- asaṁśayaṁ samagraṁ māṁ
- yathā jñāsyasi tac chṛṇu
"Now, hear, O son of Pṛthā [Arjuna], how by practicing yoga in full consciousness of Me, with mind attached to Me, you can know Me in full, free from doubt." Lord Kṛṣṇa Himself teaches how one can understand Him perfectly well, without a doubt. Not only the Pāṇḍavas but everyone who sincerely accepts the instructions of Kṛṣṇa can understand the Supreme Personality of Godhead as He is. After instructing Yudhiṣṭhira Mahārāja, Nārada Muni prays for the Lord's blessings that He be pleased with everyone and that everyone become perfect in God consciousness and return home, back to Godhead.
