Sri Chaitanya Mahaprabhu has inaugurated the Hare Krishna Movement, which is not different from Krishna, the Supreme Personality of Godhead. If one associates with this Movement, he directly associates with the Supreme Personality of Godhead. People should take advantage of the chanting of the Hare Krishna mantra and thus gain relief from all the problems created in this age of Kali. — Srimad Bhagavatam, 09.24.56.
Everything in Material world is temporary.
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.
Fulfilling the demands of the body is animal life, and fulfilling the mission of the spirit soul is the human mission.
Srimad Bhagavatam 3.3.19,
