Definitely Castenda and the Four Agreements.

My Uber llist goes something like that:

The Kybalion, The Three Initiates.
Corpus Hermeticum.
The Sirius Connection, Murry Hope and most likely anything by her.
Illusions: The Sotory of a Reluctant Messiah, Richard Bach.
The Alchemist, Paolo Coelho.
siddhartha, Herman Hess.
The Nature of Personal Reality, Seth.
Fingerprints of the Gods, Hapgod (I believe).
The Hiram Key, Christopher Knight and most books by him and his co-author sound great.

Baghavat-Gita.
Upanishad.
The Egyptian Book of the Dead and Living.
The Tibetant Book of the Dead and Living.
