Chakras are energy centres, like little roundabouts of energy along the spinal pathway. I find the concept of Chakras very helpful to understanding how our physical, mental, energetic and spiritual levels of being all interact and interelate.
There is a lot of symbolism in the traditional drawing of Chakras.
The drawings are Yantras, a way of depicting energy in a geometric form.
The chakras are drawn as flowers of different colours and numbers of petals.
Each chakra is associated with a different element: Earth. Water, Fire, Air and Space. These elements represent matter in different forms from the more solid , Earth, to the most subtle form of matter Space. Yoga philosophy and modern physics do agree that most of matter is in fact the vibration of energy in space.
I found using soft pastel on a black background helps to create an impression of energy and light.
