The lowest conceivable energy that a quantum mechanical entity can have is called zero-point energy (ZPE). The Heisenberg uncertainty principle states that quantum systems always vary in their lowest energy state, in contrast to classical mechanics. As a result, atoms and molecules continue to vibrate even at absolute zero. These characteristics also apply to the vacuum, which is a space (emptiness) devoid of atoms and molecules.
Emptiness, also known as Void or Nothingness, is a situation of "pure consciousness" in religion and mysticism wherein the mind has been cleansed of all specific objects and images. It is also a reflection or manifestation of the indistinct reality that the unfilled mind takes into account or manifests.
