Releasing Energy

Energy is the fundamental driving force behind all action: energy sets matter in motion.

The amount of energy in the mind normally fluctuates within an optimal range. When that level is exceeded then the excess energy must be expended.

I don't know if that energy is electrical or chemical, or both, or something else. However, I don't think it's necessary to know the actual physical mechanisms in order to understand the underlying principles.

There are many reasons why the mind generates excess energy. These include, but may not limited to, responses to potential danger, emotional reactions related to strong attachments, and pleasure or pain.
