The age we live in is called Kali-yuga, the age of forgetting God. It is an age of misunderstanding and quarrel, and the people’s hearts are filled with dirty things. But God is so powerful that if we chant His holy name we become purified, just as my disciples have become purified of their bad habits. Our movement is based on this principle of chanting the holy name of God. We give everyone the opportunity, without any distinction. They can come to our temple, chant the Hare Krsna mantra, take a little prasada as refreshment, and gradually become purified.
