Take your channeling and mediumship to the next level!
Just place your crystal ball in the circle, follow the instructions of the Trithemius conjuration for Drawing Spirits into Crystals (DSIC) and away you go! This board features a protective pentagram, the Greater Seal of the Archangels and Olympic Spirits, and a DSIC Table of practice.
Angels will be called to protect you during it's use and if you're used to using a scrying technique, this can be a way to ask for clarification or to double check the messages you're getting.
It's an amazing site that helped me immensely in understanding this particular operation.
The graphic used for the table of practice is this person's work that I grabbed from their website.
I was going to make something similar, but they already did a fantastic job of it. No need to reinvent the wheel.
But remember, this is just a tool...YOU are the magick. It's there to help you focus, but you still need to do the internal and external mundane work to support your practice. You can buy all the best power tools in the world, but they aren't going to build a house for you. They can make it easier, faster, deeper, more intense,, etc. but at the end of the day the buck stops with you.
