Energy Centers on the Tree of Life.

[Matt1]

The main issue with the Tarot archetypes as a means of polarization is that the adept would go far beyond simply the corrrespondences related to the symbolism on the cards and move closer towards the present experience. Thus you would be becoming the Archetypes at will and most likely visualizing them. This is commonly known as scrying on the tarot. You would meditate on a card such as the Magus, then visualize it in your minds eye, then taking it further by projecting your self as the image, thus progressively becoming the archetypes at will and polarizing in conscious without the need for external action. The polarity would simply be the desire of the adept rather than the method.

I would disagree with Ra's statement of the ipsissimus. It should surely be positive or negative based upon individual. You have the Qliphoth or the Tree of Knowledge being used by those on the left hand path, which would seem more likely to as a method for negative polarity. Again this all boils down to the conscious desire of the person doing the working. You could argue that the pantheons of demonology would have it use for the exploration of the shadow self as a means of balancing rather than a means of developing control over others and personal power.

The working is in the Subtleties of the personality. Polarity is nothing more than the conscious choice of a given moment.
