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,
The highest summit of spiritual perfection is knowledge of the Supreme Personality of Godhead.
Bhagavad Gita 10.7,
Ordinary knowledge obtained by a university education pertains only to matter. Knowledge means knowing the distinction between spirit and matter. In modern education there is no knowledge about spirit; they are simply taking care of the material elements and bodily needs.
A Devotee hears transcendental knowledge with complete willingness to surrender to that knowledge.
Bhagavad Gita is directly imparted by Krishna and if we accept Bhagavad Gita as it is, we are full of knowledge.
