Srila Prabhupada: If we simply place ourselves at the lotus feet of Krishna by taking to Krishna consciousness and keeping always in touch with Him by chanting the Hare Krishna mantra, we need not take much trouble in arranging to return to the spiritual world. By the mercy of Sri Caitanya Mahaprabhu, this is very easy. (Srimad-Bhagavatam, 7.15.53 Purport)
