Krishna is the Supreme Personality of Godhead 3

      This point is clearly stated not only in Bhagavad-gita but in all other Vedic scriptures. For example:

athapi te deva padambuja-dvaya-prasada-lesanugrhita eva hi

janati tattvam bhagavan-mahimno na canya eko ‘pi ciram vicinvan

     One can understand the Supreme Personality of Godhead by His mercy only. Anyone who has received a small particle of the prasadam—mercy—of the Lord can understand Him.

No one can understand the Lord perfectly, because the Lord is unlimited. We have limited, imperfect senses, we are subject to illusion, we try to cheat—we have so many defects. Therefore it is not possible to understand God simply by exercising our senses.

      To know “God is very good, God is great” is one thing, but by studying Bhagavad-gita we not only know “God is great,” but we see what kind of God He is, what His form is, and so on.

    We have heard from the scriptures:

ishvarah paramah krishnah sac-cid-ananda-vigrahah

anadir adir govindah sarva-karana-karanam

“Krishna, 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.”
