Paul Reps, the compiler, was an American who lived in many countries, including India, Norway, and Japan and studied many of man's efforts to find and realize his true spiritual stature. He was the author of several books of poems and prose. He once said that he felt "the equal of each grass blade and pebble and believe that it is possible to be happy though human and grown up."

Nyogen Senzaki, a Buddhist scholar of an international character to whom Reps acknowledged a deep debt of gratitude, was born in Japan. Early in life, he became a "homeless monk," wandering the land and studying from Buddhist monastery to monastery. His wanderings eventually took him to America, where for over 50 years he lived in California, with no connection with any sect, denomination, or cathedral, radiating the free and creative spirit of Zen upon all who cared to share his study, meditation, wisdom, and loving kindness.
