What the experts say about mantra meditation:
“It is as necessary to a life of growth as regular brushing is to dental hygiene.”

—Dr. John Heider, psychologist, from The Journal of Humanistic Psychology

“The ability to handle stress increases with the practice of meditation. In a culture like ours in which inner, spiritual growth is totally neglected in favor of materialistic pursuits, we might have something to learn from the Hare Krishna devotees’ meditational practices.”

—Daniel Goleman, Ph.D., Associate Editor psychology Today, Author of The Varieties of Meditational Experience
