An image , such as a tarot trump, is selected and briefly meditated upon. The magician then strikes up an imaginary conversation with whoever or whatever is in the image.
This is a natural imaginative game and has nothing to do with 'spiritualism'. Such conversations can give rise to valuable insights, information and experience; on a deeper level they may act as an interface for levels of consciousness which may not yet be accessible to the magician --- RJ Stewart (p 168 - Living Magical Arts)
