We cannot demand from Krishna to know about Him. When you actually learn to serve Him, He reveals Himself. That is the process. And the success of life is simply by pleasing Him. That is the version of all Vedic literature. Knowledge means to know Him, and success means to please Him. And how He is pleased, that can be known through the transparent medium of His confidential servant. This is the process of understanding Krishna Consciousness.
