The flavour of the song was heavily influenced by Lennon's and the Beatles' interest in Transcendental Meditation in late 1967 – early 1968, when the song was composed. Based on this, he added the mantra "Jai guru deva om" (Sanskrit: जय गुरुदेव ॐ) to the piece, which became the link to the chorus. The Sanskrit phrase is a sentence fragment whose words could have many meanings. Literally it approximates as "glory to the shining remover of darkness" and can be paraphrased as "Victory to God divine", "Hail to the divine guru", or the phrase commonly invoked by the late Maharishi Mahesh Yogi in referring to his spiritual teacher, "All glory to Guru Dev".
