Series forms a giant Sephirotic Tree in the sky and each Eva assumes the role of a sephirah. Shinji appears at the sephirah of Tiferet, at the time of his metaphorical sacrifice. Slant Magazine Micheal Peterson noted that Tiferet in the Kabbalah is identified with Christ on the cross, and thus to the place where the sacred meets the profane. Anime Invasion magazine also noted 16th-century Jewish mystical writings predict a decline of the divine light in every human being, followed by the destruction of humanity in a catastrophic event. Eva-01 transforms into the Tree of Life, which an official pamphlet on the film links to the inverted tree of the Kabbalah and a similar tree found in Hindu scriptures. Seele thus names a "Red Earth Purification Ceremony", which name is linked to theories about the etymology of the name Adam according to which it means "earth", "red".

Scenes from the film have been interpreted as a representation of Shinji's sexual instincts, such as those in which he sees Asuka in bed or Misato having sex with her lover Ryoji Kaji. Other scenes have been interpreted as a representation of his death drive, such as the one in which he destroys a sand pyramid and the one in which he strangles Asuka and childish drawings of dead animals appear. According to writers Kazuhisa Fujie and Martin Foster, the lyrics of the film's two songs
