What if I Don’t Believe in or Understand Mantra Meditation?
Fortunately, the Hare Krishna mantra works whether we believe in it or not. We don't have to understand or believe in medicine for it to work, and the science of chanting Hare Krishna is subtler than any chemical process. It has a profoundly beneficial effect on the consciousness, whether or not one is aware of the science at all. Try it and see.
