Vedanta is the last word in Vedic wisdom, and the author and knower of the Vedanta philosophy is Lord Krishna; and the highest Vedantist is the great soul who takes pleasure in chanting the holy name of the Lord. That is the ultimate purpose of all Vedic mysticism.
Bhagavad-gita 2.46,
Srila Prabhupada
This crying is the last word in the progressive path of devotional service. One who can cry for the Lord in love is certainly successful in the line of devotional service. — Srimad Bhagavatam, 03.04.35.
By chanting Krishna’s Holy Name, one cleanses all the dust from the mirror of one’s consciousness.
