In late January 1966, Coltrane and his group, which included saxophonist Pharoah Sanders, pianist Alice Coltrane (McCoy Tyner had left the group at the end of the previous year[2]), bassist Jimmy Garrison, bassist / clarinetist Donald Rafael Garrett, and drummers Elvin Jones and Rashied Ali, arrived in San Francisco for a two-week gig at the Jazz Workshop, sharing the bill with Thelonious Monk's quartet.

[6]) "Reverend King" begins and ends with chants of "Aum-Mani-Pad-Mi-Hum" and features a solo by Sanders on tenor, as well as one of John Coltrane's few recorded appearances on bass clarinet.

[8][9] These were her first recordings as a leader,[10] and feature bassist Garrison and drummer Ben Riley, with Sanders appearing on tenor sax on "Lord, Help Me to Be" and briefly on flute on "The Sun".

"[12] Thom Jurek, also writing for AllMusic, wrote "While this record holds up quite well... it is still a minor Impulse album compared to some of the saxophonist's master works.

"[10] John Corbett included the album in his book Vinyl Freak: Love Letters to a Dying Medium, referring to "Manifestation" as "beautiful energy music, as Coltrane knew how to craft it" and expressing admiration for "Reverend King"'s "gloriously ecstatic bass clarinet — another underdocumented facet of Trane’s recorded history — and... joyous group interaction by the full ensemble.
