While in Denmark, the Lennons, Cox and the latter's current partner, Melinde Kendall, discussed the concept of "instant karma", whereby the causality of one's actions is immediate rather than borne out over a lifetime. Author Philip Norman writes of the concept's appeal: "The idea was quintessential Lennon – the age-old Buddhist law of cause and effect turned into something as modern and synthetic as instant coffee and, simultaneously, into a bogey under the stairs that can get you if you don't watch out." On 27 January, two days after returning to the UK, Lennon woke up with the beginnings of a song inspired by his conversations with Cox and Kendall. Working at home on a piano, he developed the idea and came up with a melody for the composition, which he titled "Instant Karma!"
