2.  The Energy Plane between the Physical and Astral planes. Its energies are in constant movement, like tides and currents, ruled by the Moon, Sun, and Planets and moving in cycles. In theory and practice, the etheric is considered to be the upper "layers" of the physical plane and consists of substance and energy not perceptible to the "hard" physical senses. However, its substance and energy permeates the physical plane and the physical body to provide the life force—mostly "regulated" by the Moon and Planets—that enlivens all physical life.
