Heard was a guide and mentor to numerous well-known people in the 1950s and 1960s, including author Aldous Huxley, Henry Luce, Clare Boothe Luce, and Bill Wilson, co-founder of Alcoholics Anonymous. His work was a forerunner of, and influence on, the consciousness development movement that has spread in the Western world since the 1960s. (Sourced from Wikipedia May 2023)
