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,
A Devotee hears transcendental knowledge with complete willingness to surrender to that knowledge.
Real knowledge is expounded in Bhagavad-gita: “Just become Krishna conscious. Just worship Krishna and become a devotee of Krishna.”
Srimad Bhagavatam 3.24.18,
Without perfect knowledge, one cannot act perfectly.
