Beginning of all knowledge comes from humility.
Whatever knowledge we acquire should be used in Krishna consciousness.
Vedanta means ultimate knowledge. Knowledge is never perfect unless one comes to the point of understanding Krishna. To remain in Krishna Consciousness is actual understanding of Vedanta.
Letter to Janardana — Los Angeles 21 January, 1968,
Knowledge of Krishna is such a great gift that it is impossible to repay the benefactor.
Srimad Bhagavatam 4.22.47,
