Okay.. This is from my coven, but I am moving it out here as well..
Unit 1: Background Information: A shrouded history
Scrying is an art as old as belief in the presence of otherworldly beings itself, and probably older still, however, there are no lasting records to tell us such. Scrying is the conscious use of outside media to contact our unconscious minds to access information that would otherwise be outside of our range of knowledge. Scried "images" can be more than just sight, and oftentimes there is no vision involved in what you scry. You can sometimes hear things, smell, and even feel the subject of the scrying. The only issue is that your unconscious mind is not sure how to give the information in a way we would understand it, so oftentimes we must meditate on the "images" (i say images, but i mean anything that you scry..) so that we can know what it is that we are actually being given.
This wraps up part 1, and I will post part 2 later. Please comment and leave feedback if you wish.
