Many people use the terms energy and force interchangeably. However, for Toltecs, they are not the same.
What Toltecs call energy is the product of power. Power itself is the product of perception. Therefore, for Toltecs, energy is related to evolving awareness, and has a spiraling quality.
A force, on the other hand, is related to the inherent awareness of life, and is linear in quality.
In trying to differentiate between a force and energy, one might compare a bullet with something with its own momentum, like a car. It is within our possibility to change our awareness, (direction of car), as we evolve. This is the nature of evolving awareness, and of energy. However, we cannot change or affect forces. We simply have to live with them until they have run their course.
