Since spirituality was included in the original quest, I may recommend the following list... those books include a variety of ways... some of them not recommended for everyone (esp. 6 and 7)
1) Rastafari - The New Creation by Barbara Makeda Blake-Hannah (2003 edition)
Definitely uplifting, and very interesting. Includes topics like the Bible and The Ark of Covenant. You can find it at
www.onedropbooks.com
2) The World is Sound: Nada Brahma: Music and the Landscape of Consciousness by Joachim Ernest Berendt. Destiny Books (May 1st, 1991)
I read this book when I was 17 and it blew me away.
2) The Upanishads by F. Max-Muller (Translator)
Wordsworth Editions Ltd (March 23rd, 2000)
ok, its a primary religious text, so let me mention the following one as a secondary..
Commentaries on the Vedas, the Upanishads and the Bhagavad Gita: The Three Branches of India's Life-Tree by Sri Chinmoy
Blue Beyond Books (Dec. 31st, 1996)
3) Zen (Colour Book Series) by Toichi Yoshioka, H. Maezumi (Translator) Japan Publications Trading Co (Oct. 27th, 2000)
Good introduction to Zen schools and theory on meditation.
4) Cosmic Canticle (Us) by Ernesto Cardenal, John Lyons (Translator) Curbstone Press (Dec. 1st, 1993)
Cardenal is one of the most famous poets and priests of Latin America. He actively followed liberation theology.
5) Abide in Love by Ernesto Cardenal, Mev Puleo
Orbis Books (Aug. 1st, 1995)
6) Grimorium Verum
..dating back to 1517, very interesting, but practically impossible to find. I found a part of it though.. a word of warning, be careful with all Grimoires, there are several others out there which may be easier to find (18th century etc.) ..they deal with dark stuff.
7) Voodoo, Past and Present by Ron Bodin, Univ. of Southwestern Louisiana (Dec. 1st, 1990)
Good book I found in New Orleans. Only recommended if you are interested in Voodoo.
8) back to India.. just reading The Great Secret - Talks on the Songs of Kabir, by Osho, a spiritual master from India. There are some very beautiful parts, like a part of the "Tale of Love" that I have blogged (yes, in english!) at

9) Healers on Healing (New Consciousness Reader) by W. Brugh Joy, Jeremy P. Tarcher (Feb 1st 1989)
Just reading that one..
As to primary texts, the Kaballah should be included, and I am trying to find the 6th and 7th book of Moses.
