A student went to a saint and asked, “Master, tell me how can I protect my soul from the snares of the devil.”
Without a word, the saint lit a candle and told him, “Put your hand over the flame.”
“Oh, no, Master,” said the student. “The flame is so hot that it would burn my fingers.”
“Anyone who wishes to be unconquered by evil must first enkindle the flame of love of God in one’s heart,” the saint said, “the devil cannot touch a soul that is afire with love of God.”
Srila Prabhupada explains, “Krishna consciousness is such a transcendentally nice thing that automatically material enjoyment becomes distasteful. It is as if a hungry man had satisfied his hunger by a sufficient quantity of nutritious eatables.” (Bhagavad-gita 2.60, purport)
Srila Prabhupada also says, “The process is very simple. Simply by chanting the holy names of God – Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare / Hare Rama, Hare Rama, Rama Rama, Hare Hare – one cleanses the dirt from his heart and gains understanding that he is part and parcel of the Supreme Lord and that it is his duty to serve Him. This process is very pleasant: we chant the Hare Krishna mantra, we dance rhythmically, and we eat nice prasada. While enjoying this life, we are preparing to enter into the kingdom of God in our next life.” – Easy Journey to Other Planets
