Simply by chanting the holy name of Kṛṣṇa one can obtain freedom from material existence. Indeed, simply by chanting the Hare Kṛṣṇa mantra one will be able to see the lotus feet of the Lord.
(Sri Caitanya Caritamrta------1:7:73-------translation).

When a person who chants the holy name is liberated, he attains the ultimate perfection by returning home, back to Godhead. In the words of Śrī Caitanya-caritāmṛta (CC.1:7:73):
kṛṣṇa-mantra haite habe saṁsāra-mocana
kṛṣṇa-nāma haite pābe kṛṣṇera caraṇa
"Simply by chanting the holy name of Kṛṣṇa one can obtain freedom from material existence. Indeed, simply by chanting the Hare Kṛṣṇa mantra one will be able to see the lotus feet of the Lord."

(Sri Caitanya Caritamrta------2:15:108------purport).
