This is a site created by Rowena Kryder, whose brilliant "Gaia Matrix Oracle" cards and book set have really helped me in my personal path. I highly recommend these cards (Volume I, Volume II is the companion book), although they are out of print, and may be difficult to find. However, they are still out there if you look around, and you will not be dissapointed. They are a deep tool for exploring how your personal Spiritual work relates to cultural revolution/evolution.
