Chanting Krishna’s Holy Name
The chanting of the holy name of Krishna expands the blissful ocean of transcendental life. It gives a cooling effect to everyone and enables one to taste full nectar at every step.
Sri Chaitanya Caritamrta,
Antya Lila, 20.12
Krishna and Maya
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.
Effect of Chanting The Hare Krishna Maha Mantra
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.
