Illusions by Richard Bach (ISBN 0-440-20488-7)

Illusions is a mystical first person narrative of a lonely biplane pilot, who makes his living by selling air rides for $3 for ten minutes. He gets an imaginary friend and Messiah called Donald Shimoda, with whom he tries to reconcile the preachings of the Bible, the modern physics and the Indian mystic concept of Maya (illusion).
Twice in this narrative the imagery of this imaginary friend borders at schizophrenia. Once when he meets the Vampire and the other time Don is assassinated. The two underlying Christian beliefs, that is of the second coming of Jesus and the violent death that the Messiah must suffer for the salvation of the humankind; are intricately woven in the story. The Indian concept of Maya (Illusion) and that of concept of rebirth is also used as the fabric of the narration.
Richard introduces two innovations that of the God is not referred as He but Is. The second being that imagination is sought to replace faith as the foundation of one's religion.
He attempt to straighten the triangle into a straight line. The vertices's of the triangle being Maya, Christianity and science.
Overall a readable book, if one is comfortable with the concept of Maya.
