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,
Srila Prabhupada
Only to those great souls who have implicit faith in both the Lord and the spiritual master are all the imports of the Vedic knowledge automatically revealed.
Spread the glories of Lord Krishna in every town and village all over the world.
Caitanya Mahaprabhu has recommended that everyone chant the Hare Krishna mantra just to cleanse the dust from the heart. If the dust of the heart is cleansed away, then one can actually understand the importance of the holy name.
