The modern subconscious has been so filled up with media, conditioning, schooling, parenting and working that it must be one of the most dense information stores in the history of the universe. The thing is that we are not really provided with any nets or fishing gear at the moment (that’s what shamans etc were good for), and the things found in its murky depths are not taken to be of any value.
By looking into sources of information noise, such as random wikipedia sources (method) and looking within yourself, you stir these waters and can see thoughts as the arise to the surface from the pressurized depths. These strange creatures are the whole basis for our civilization, culture.
This is a great tool to explore your own inner and outer reality.
Its just like tarot cards. They are just symbols on a page, with no actual absolute value. The interpretation of each card changes from person to person, even in subtle ways. The literal meaning of the cards is not the important bit. How these random media work is that they stir the mind in unexpected and unpredicted ways, and allow fresh insights to emerge. Signal from noise.
