Harrison and Boyd returned to England on 22 October , and continued to adhere to a Hindu-aligned lifestyle of yoga , meditation and vegetarianism at their home in Esher . The education Harrison received in India , particularly regarding the illusory nature of the material world , resonated following his experiences with the hallucinogenic drug LSD ( commonly known as " acid " ) and informed his lyrics to " Within You Without You " . Having considered leaving the Beatles after the completion of their third US tour , on 29 August 1966 , he instead gained a philosophical perspective on the effects of the band 's international fame . He later attributed " Within You Without You " to his having " fallen under the spell of the country " after experiencing the " pure essence of India " through Shankar 's guidance
