A ccording to Buddhism, the whole universe is a single, dynamic web of energy which can exist in three forms. These three forms of energy that exist in the universe also exist in the human body.
Energy in the universe can exist are: 1.
Free Energy, 2.
Forces, 3.
Matter.
Free energy is pure, undifferentiated energy. Therefore, this form cannot be perceived directly or indirectly. Free, undifferentiated energy exists in the human body as consciousness. In Buddhism, consciousness is described as Vinnana.
Forces are a type of differentiated energy produced by moving matter, which in turn causes movement of matter. The forces that exist in the universe are: 1. Electricity, 2. Magnetism, 3. Gravity.
These forces do not exist in the material form. (i.e. particles or waves). Their existence is in the form of an energy field which can be detected indirectly.
By these forces, the movements that occur in all matter in the universe are inter-connected.
