Who is Lord Kṛṣṇa, and what is His original form? Unless one knows about His opulence, potencies, fame, beauty, knowledge, and renunciation, one can never enter into the realm of pure devotional service. As stated in the Caitanya-caritāmṛta (CC Adi 2.117),
- siddhānta baliyā citte nā kara alasa
- ihā ha-ite kṛṣṇe lāge sudṛḍha mānasa
A sincere student should not neglect the discussion of such philosophical conclusions, considering them controversial, for such discussions strengthen the mind. Thus one's mind becomes attached to Śrī Kṛṣṇa.
