Zero Point Energy is a vibrational energy in which the energy particles retain even at the absolute 0 of temperature. Hatha yoga - hot and cold in the body. If we are too used to heat, we don't understand cold. If we are too used to cold, we don't understand heat. Temperature in physics has been found to be a measure of the intensity of random energy motion, in various directions, whether spirit or body, as temperature is reduced to absolute zero, sound of silence, no hot or cold, all motion ceases and energy come to rest. However, the motion, nada yoga, sound of silence, corresponding to zero-point energy never vanishes.
