It's very difficult to talk about energies and entities and their effects without conjuring up the dualistic mindset that is such a strong part of the Western mind. Anyway, we're going to be talking mostly about energies rather than magick per se. This confusion is so innate in our thought patterns that they have infected Western use of the concepts of yin and yang as well. The terms I am going to use come from my training in music. A consonant interval is one that sounds pleasant and stable.
Music is very relativist that way.
No other value judgements are added. Before you can work with the natural energies around you, you have to become aware of them. Even without that, though, you may receive intuitive impressions. I would have colors and shapes pop into my head, and these would be accurate enough, though less entertaining. You may also develop physical responses to energy if you are in a quiet state and are paying attention.
