Maya (illusion in sanskrit), is a princess who has been challenged to discover her true self-identity via voyages in a crystal ball, a gift she mysteriously received from “Prince Karma"; the latter wished her a safe trip and asked her not to forget her princedom. Alas! her journey begins on planet Earth as a secretary in a giant cosmetic corporation where she soon forgets that she is a princess from another world.
The story is embedded with symbols based on the Yoga Philosophy as well as the Biographical Work principles (a spiritual coaching technique).
"How can I be sure I am a butterfly who dreamed he was human, and not a human dreaming right now that he is a butterfly?" from the first chapter of the book.
