By chanting Krishna’s names, one will be transferred to the supreme planet, Krishnaloka, without a doubt.
"On one's own, it is impossible to conquer Maya and leave her behind. There is no means to do it other than through the grace of the saints."
Devotional service to Krishna is the chief function of the living entity. There are different methods for the liberation of the conditioned soul Karma, jnana, yoga and Bhakti but all are dependent on bhakti. — Sri Caitanya Caritamrita, Madhya lila, 22.17.
