Last year I took a class on Scrying taught by Harper Feist. It was a fascinating course that explored the sensory aspects of scrying in relationship to our senses.
Not just the five senses of sight, sound, taste, touch, and smell, but also kinisthetic, thermal, and other more subtle senses all of us have access to, including of course the "psychic senses."
Since taking that course, I've been continuing to experiment with scrying and have made it a regular part of my practice.
Even before I took the class I had done some scrying with bowls of water and with a crystal globe, but after taking the class I added a couple of tools to my scrying practice.
I bought a black scrying mirror and I started adding candles to the mix in order to create a source of light.
