and then I though I might be able to see if I have copies of the speeches those quotes of young GMJ came from and lo and behold I sort of did.

They were in a newspaper article called "Pretty Far-Out Little Dude" which was recorded in a pamphlet "Report of the World Peace Tour of Balyogeshwar Shri Sant Ji Maharaj" of 1971 so maybe Sullivan didn't have perfect recall but they found appropriate quotes

The Report is pretty interesting
