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.
Living beings who are entangled in the complicated meshes of birth and death can be freed immediately by even unconsciously chanting the holy name of Krishna, which is feared by fear personified. — Srimad Bhagavatam, 01.01.15.
Simply by chanting the Hare Krishna mantra one revives his original relationship with God.
Srimad Bhagavatam 7.7.39,
Krishna is present fully in His holy name and this is realized by the humility and sincerity in our chanting.
If one wants to derive the actual benefit from this human form, he must take to the chanting of the holy name of the Lord.
Srimad Bhagavatam 7.6.19,
