Everything flows out and in; everything has it's tides; all things rise and fall; the pendulum swing manifests in everything; the measure of the swing to the right is the measure of the swing to the left; rhythm compensates.
The principle of rhythm explains the cycles of life, the truth that everything has a tide-like ebb and flow. Hermes states that the ebb of the tide is equal to its flow and is set in motion and maintained by the rhythm of the universe. There can be no better example that than that of the various cultures and their civilizations. Within every great experience, whether related to culture or civilization, the tide must eventually turn. This principle is eternally united with the concept of the great, awe-inspiring cycles or ages of humankind, as well as those of the Earth, which forever dictate periods of upheaval and tranquility. There is always an action and a reaction, an advance and a retreat. This law manifests in the creation and destruction of worlds, the rise and fall of notions, and ultimately in the mental states of humanity.
