Guided visualization is interesting tool. There are seminars people do this with Tarot and it can be very interesting at times. However, there is one more interesting thing that the old Orders used to do some time ago. That is, we "guide" the visualization 40-50% of the way and we let the other 60-50% develop by themselves.

So for example, we decide to walk the path of Severity to Mercy, Gevurah to Chesed that is sometimes shown as Justice(other ways to view it as well). We imagine we step through the card for example and we observe, allowing what we need to change to change. Lets say we end up in a very big courtroom corridor with lawyers and prosecutors rushing in to work on cases in the smaller rooms on the sides, with a marble black and white floors and giant statue in front of us similar to the artwork on the deck we use.

Or maybe in an old kingsroom where the King had to decide a case between his ministers, so a very different setting and one that is solely decided by one, although again based on purely human decision of what is appropriate and what isn't.

If we could allow these setting to show up by itself that is even nicer, but even if we decide to choose it or base it exactly on the cards, after we are there the important factor is to act like in the real world, there is some part of this that comes from us, what we think and see, how we feel etc. and that we can choose, but to be able to let go and not control what happens outside. Someone may come to talk with us, or some event may happen that shows us what we need to know. Some of the rooms may call to us and lead elsewhere etc.

That was called "working with the paths". We can see the Tree of Life as reflecting the processes around us and based on what we have problems with we can walk the paths there to understand it fully, deeply and balance it out. And again, while guided visualization is very interesting, its important to allow big part of what we see to come in spontaneous and not controlled way, as that is a more direct and powerful way of divination.

Similar to I Ching/Yi Jing where we have text for some active lines and the idea if we have more then one active we have to make the text ourselves, one can say we have some Images on the cards as a guide in what direction we may want to start, but the actual images we divine based on can come in a more free and unbiased way.

There are schools relate dto Kabbalah that work a lot with that, there are rules to it. For example if one sees a dark place they don't want to go in, they should go in imagining they are protected. And other stuff like that, more info in some topic somewhere around the forums. But even if one does it without rules in a more free form can still be very beneficial for understanding stuff, in my humble view. : )
