The Mantram Handbook describes methods of using a mantram — sometimes called a Holy Name — in daily living. Benefits are also described. Written by Eknath Easwaran, the book was originally published in the United States in 1977. Several subsequent editions have been published, sometimes under different titles, in the United States, the United Kingdom, and India. Foreign (non-English) editions have also been published in several languages. The book has been reviewed in newspapers, magazines, and websites, and discussed in professional journals. It has also been a focus of scientific research. The subtitle of the fifth (2009) US edition is: a practical guide to choosing your mantram & calming your mind.
