I am giving clairvoyant readings at school, it can be a lot of fun when you get past the stage fright. It took me a while to get started because I kept trying to force a dialogue with my spirit guides and they don't really communicate with me that way. I do a lot better with guided meditations and just keep an eye on all the images and scenes that go by. The clairvoyance comes easily when you relax, the tricky part is learning to interpret the message.
For example, a couple weeks ago I saw my sitter traveling halfway across the world on a spiritual holiday. She was very excited to go on this journey and had sturdy walking boots to symbolize a challenging trek. In my meditation I saw her going to a temple in Asia, it was very peaceful and fulfilling for a few seconds and then a Samurai warrior appeared on the scene. His energy was combative, it seemed like he was ready for a battle and waiting for it to start.
I tried to bring my mind back to the tranquility of the monks but it just went back to the Samurai, I felt like I should enjoy the tranquility of the monks but the aggressive Samurai spirit didn't let me. After a few minutes I gave in and just let the images switch back and forth between peace and war. I almost dismissed the struggle as a product of my imagination, but when I mentioned this to my sitter she confirmed that she actually felt this way in her life.
Even during the reading my logical mind was still trying to convince her to consider a trip to Asia, or to take up a Buddhist practice. Looking back on it, the Asian backdrop had more to do with my own subconscious than with the message I was supposed to give her. I spent an hour at the British Museum looking at Samurai swords and Buddhist sculptures last week, and just yesterday I bought a book by a Tibetan master. This scene served as a backdrop for the real messages: the inner struggle, the spiritual journey and expansiveness of the horizon. All of these were based on feeling evoked by the images, not by the images themselves.
