Dick realizes our spiritual lives are intertwined with the ecosphere, so rejecting the spiritual aspect of our existence means giving up on our physical lives.
His vision of Tagore is based on a combination of Eastern and Western thought, beginning with the Western concept of man’s fall from the Garden of Eden and a need to return to that state, but with the Eastern solution of acknowledging suffering (which was caused by man in the Western view) and withdrawing from the world in order to repair it.
He has a dream/hypnagogic vision of a stigmata on his own leg that represents Tagore’s wound. He identifies with Tagore who can only get relief from the self-inflicted pain when the injuries to the ecosphere have stopped.
Dick admits he has a messiah complex and sees himself as one with the ecosphere. It is his body and mind which are being poisoned by humans who are not living in harmony with it. He understands that Tagore is a man, not a deity. Tagore is either the Buddha or a Buddha, and he represents the ideal we should all be striving toward.
In a “tremendous breakthrough” Dick realizes that his 2-74 experience was a “conjurer’s trick.” Because Dick believed in Christianity he attached the significance to the Jesus fish necklace, which led to the cascade of other events. It was all an illusion that pointed to the Buddhist truth about the nature of reality. For the following year he interpreted things through the lens of Christianity without seeing what was really there.
With his vision of Tagore he seems to have anticipated the “no-nukes” protests going on in the 80s, turning his spiritual belief into a political one.
