An accomplished pianist and one of the few harpists in the history of jazz, Coltrane recorded many albums as a bandleader, beginning in the late 1960s and early 1970s for Impulse! and other record labels. She was married to the jazz saxophonist and composer John Coltrane, with whom she performed in 1966–1967.One of the foremost proponents of spiritual jazz, her eclectic music proved influential both within and outside the world of jazz.

Coltrane’s career slowed from the mid 1970s as she became more dedicated to her religious education. She founded the Vedantic Center in 1975 and the Shanti Anantam ashram in California in 1983, where she served as spiritual director. On July 3, 1994, she rededicated and inaugurated the land as Sai Anantam Ashram. During the 1980s and 1990s, she recorded several albums of Hindu devotional songs before returning to spiritual jazz in the 2000s and releasing her final album Translinear Light in 2004.
