Chant And Be Happy is an introduction to the history, practice, and benefits of mantra meditation, and specifically the significance of chanting the Hare Krishna mantra. Also known as the maha-mantra, "great chant for deliverance," Hare Krishna is recommended in many sacred texts as the most effective form of meditation for the present age. Since the 1960s and '70s, this mantra has gained world popularity, partially due to its inclusion in the #1 song "My Sweet Lord" by George Harrison.
The book contains a conversation between the Hare Krishna movement's founder Srila Prabhupada, John Lennon, George Harrison, and Yoko Ono on what makes a mantra genuine and effective. It also discusses the scriptural origin of the mantra, as well as step-by-step instructions for chanting.
