Mascaró had sent George Harrison a copy of the book in mid-November 1967 in response to a letter from Harrison. Mascaró's accompanying letter explained that he had recently been introduced to The Beatles song "Within You Without You" by friends and had been moved by the song's message. In a post script, Mascaró wonders if it "might not be interesting to put into your music a few words of Tao" before suggesting selection 48 from his book (rendered by Mascaró). Harrison travelled to Bombay, India in January 1968 to record Indian musicians for the soundtrack of a film, "Wonderwall". During these sessions he also set Mascaró's suggested passage to music. After some additional work in London the following month, the song was released as a B-side to the single "Lady Madonna" on 15 March 1968. Mascaró had first met Harrison on 4 October 1967 when they both appeared on "The Frost Programme" television show. Harrison and John Lennon were brought in to discuss Transcendental Meditation (TM) with a panel of experts that included Mascaró, Dr. John Allison, a group of Quakers and the author and lawyer John Mortimer, who took the atheistic side of the debate.
