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 with 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.
