Krishna is compared to sunshine and maya is compared to darkness. Wherever there is sunshine, there cannot be darkness. As soon as one takes to Krishna consciousness, the darkness of illusion (the influence of the external energy) will immediately vanish.
Simply by chanting the holy name of Krishna one can obtain freedom from material existence.
Sri Chaitanya Caritamrta,
Adi Lila 7.73
To promulgate prema-bhakti [devotional service in love of Godhead], Krishna appeared as Sri Krishna Caitanya with the mood and complexion of Sri Radha.
The holy name of Krishna is so attractive that anyone who chants it — including all living entities, moving and nonmoving, and even Lord Krishna Himself — becomes imbued with love of Krishna. This is the effect of chanting the Hare Krishna maha-mantra.
Chaitanya Caritamrta, Antya Lila 3.268,
