Lord Sri Krishna is the original Supreme Personality of Godhead who is accepted by all great authorities like Narada, Vyasadeva, Lord Caitanya, Siddhanta Sarasvati, Bhaktivinode Thakura, Lord Caitanya, Arjuna and many countless other acaryas.

mattah parataram nanyat
kincid asti dhananjaya
mayi sarvam idam protam
sutre mani-gana iva

O conquerer of wealth [Arjuna], there is no Truth superior to Me. Everything rests upon Me, as pearls are strung on a thread. [BG 7.7]

isvarah paramah krsnah
sac-cid-ananda-vigrahah
anadir adir govindah
sarva-karana karanam

Krsna who is known as Govinda is the Supreme Godhead. He has an eternal blissful spiritual body. He is the origin of all. He has no other origin and He is the prime cause of all causes. [Brahma Samhita]

To understand Lord Krishna, one has to follow in the footsteps of great acaryas. No one can speculate upon Krishna, neither can he be known by such speculations. Tad vijnanartham sa gurum eva abhigacchet [MU 1.2.12]
