I'd like to share with you some of my new understandings about four elements, Yin-Yang and our practice, arrived after listening to an interesting Dhamma talk by Ajhaan Martin Piyadhammo on four elements last summer:
One mechanism of the composition of the nature: this universe, from the smallest particle to the largest cosmos, is made of the 4 parts – solid matter, connecting and conducting matter, energy matter and moving matter, all of which are natural elements. The natural elements are all composed of neutrons (neutral), protons (positive) and electrons (negative), the same pattern as the feelings (interesting that nama and rupa have the same pattern). The Chinese Yin-Yang theory (Taiji) might need to be revised a bit, with neutral gray color added in the centre in between the half white and the half black circles. It’s so fascinating that the nature appears to use the same mechanisms for the Dhammas in the universe.
So all the different matters actually differ only in the number of protons, neutrons and electrons. Seeing the essence of things instead of their appearance could help us overcome greed and aversion. And seeing further that even such essence is empty (anatta) could help us overcome delusion.
