Hi Brendan,
I came upon your site again. Some books that I really like are Siddhartha by Herman Hesse, the Tao Te Ching by Lao Tsu, and just for fun escape the Skylark series and the Lensman series by E E Doc Smith. An author that has been exploring the scientific nature of spirit, consciousness, time and the daemon is Anthony Peake. Am having fun exploring these things and growing my spirit. Best wishes, your friend, Theodore
