The Tarot

I'm relatively new to the Tarot and have recently began studying. It is promoted as great tool for contemplation and meditation that many use to get in touch with their sub-conscious. Some gnostics use it in this manner as a tool for praxis. A lot of the symbols come from the Golden Dawn and the Kabbalah. The Golden Dawn derived much of their symbols from earlier alchemical knowledge.

Each of the 22 major arcana have been mapped to the 22 paths between the sephiroth on the Tree of Life and as such they can be seent to represent the "movement" between the various realms between heaven and earth. The language of the conscious mind is through language where words mean very specific things. Conversely the sub-conscious mind seems to work well with symbols. In the west most of us have developed our left analytical mind at the expense of our sub-conscious mind.

It is the working with symbols that are designed to stimulate and interact with a part of ourselves that we aren't usually directly aware of that the Tarot is used for.

I have found these books pretty informative in the use of Tarot in a contemplative fashion:
The Kabbalah Experience and The Watkins Tarot Handbook both by Naomi Ozaniec

It should be clear that the sacred images of the Tarot serve a spiritual purpose. In common with the vast variety of worldwide spiritual icons, the sacred images of the Tarot serve to feed the contemplative and reflective instincts and as such have rightfully earned a place within the spiritual traditions of the west. The sacred icons of the Tarot form a key aspect of a Mystery School curriculum as doorways leading into the realm of ageless Wisdom. This is the deeper gift of the Tarot.
