In 1968, The Beatles went to Rishikesh in northern India to study meditation with the Maharishi Mahesh Yogi. They were all big on spirituality and expanding their consciousness. In 1967, George Harrison was interviewed by the International Times about his thoughts on God and the meaning of it all. One thing Harrison was excited to talk about was “the buzz of all buzzes,” and how to attain it naturally.
Harrison told his interviewer, Barry Miles, that communicating with people reminded him that “we are all one.”
“Communication, just the realisation of human love reciprocated, it’s such a gas, it’s a good vibration which makes you feel good,” he said, as recorded in the book George Harrison on George Harrison.
In addition to simply talking to people, Harrison was passionate about the feelings elicited via chanting.
