Living in Karachi, Pakistan, Abdul Aziz can be attributed with sparking Merton's first interest in Sufism, an interest later shared with his novices at Gethsemani. Beginning their correspondence in late 1960, Merton and Aziz would exchange books and ideas. Aziz was introduced to Merton's work through Louis Massignon, a mutual friend. An important insight from these letters is Merton's response to Aziz's request for a description of his prayer life.
