“There is no way to happiness. Happiness is the way.”
Thich Nhat Hanh (1926) Religious leader and peace activist
The source is likely to be either modern Buddhist monk Thich Nhat Hanh, or Calvinist clergyman Abraham Johannes Muste. The phrase appears in Thich Nhat Hanh's writings; but it also appears in a volume of US senate hearings from 1948, when Thich Nhat Hanh had not yet been ordained as a monk. Muste is known to have used a variant of the phrase – "'peace' is the way" in 1967, but this was not the first time he had used it, and he had a connection with the 1948 hearing.
