"That Is All" is a song by English musician George Harrison released as the final track of his 1973 album "Living in the Material World". A slow, heavily orchestrated ballad, it is one of many Harrison love songs that appear to be directed at either a woman or a deity. Harrison wrote and recorded the song during the height of his public devotion to Hinduism; on release, "Rolling Stone" described its lyrics as "a sort of Hindu "In Paradisium"". George Harrison wrote "That Is All" over 1971–72, a period marked by both his heightened devotion to Hindu spirituality and his commitment to providing humanitarian aid for the refugees of the Bangladesh Liberation War. With his own career taking second place to the latter endeavour, following the Concert for Bangladesh in August 1971, Harrison's musical activities included helping American musician Gary Wright establish himself as a solo artist. Wright's album "Footprint" was released in November that year and included "Love to Survive", a song that author Simon Leng cites as having been an influence on Harrison's composition "That Is All". "Love to Survive" was orchestrated by Harrison's "All Things Must Pass" arranger, John Barham, who says that "musically there was a strong rapport" between himself, Harrison and Wright at this time. The friendship was also based on a shared interest in Eastern spirituality, after Harrison had given Wright a copy of "Autobiography of a Yogi", a text that Ravi Shankar had introduced to Harrison when he visited India in 1966.
