Into the Mystic

Morrison said he first wrote the title as Into the Misty and changed it because the song seemed to have something ethereal about it. He explained that the lyrics work two ways through words that sound alike, such as born and borne before the wind, and that the song is just about being part of the universe. Johnny Rogan wrote that the wording conjured the shipyards of East Belfast as well as the astral plane, with Morrison's saxophone imitating a foghorn. Greil Marcus and Lester Bangs called it the heart of Moondance in Rolling Stone.

The original 1970 LP pressings use a mix from 10 December 1969 with a prominent tambourine. Later pressings and CDs before 2008 use a mix from 5 January 1970 without the tambourine and with a more muted foghorn sound, and the tambourine mix was restored on a 2008 reissue and the 2013 remaster. A live version, 4:33 long, appears on It's Too Late to Stop Now, and the album's closing words gave it its title. The song appears in 283 of the 2,253 logged setlists that list songs.

Rolling Stone put it at number 474 in its 2010 list of the 500 greatest songs. A BBC survey found it among the most popular tracks for surgeons to listen to while operating. Bob Dylan covered it in Alicante, Spain, on 15 June 2023.
