Between classes and meditation sessions, the Beatles had plenty of free time. They brought some instruments with them, including acoustic guitars, and began to write new songs. "We wrote "tons" of songs in India," John Lennon later told "Playboy" magazine. Their wives and girlfriends also came along to India. Lennon and his wife Cynthia did not spend much time together. He would leave alone in the morning, to pick up the mail. It turned out he was receiving letters and postcards from Yoko Ono, a Japanese artist friend, and did not want Cynthia to know. He said later that while he was in India, he began to think about Ono "as a woman, not just an intellectual woman", and that he might want a romantic relationship with her.
