8/10
may be a higher score even - i dont know, am not sure what the criteria are, but i have found the book by E. A. Koetting "Questing after Visions: Making Conscious Contact" excellent and very helpful - helpful because i found his detailing of the experience of going into altered states more elucidating - it goes into the mechanics of having visions and there is much in the way of astral travel and scrying that is discussed . - i am still reading it at the moment, but have found its section on the use of Tattwa cards also good and easy to pick up
