Linguistically, emptiness is the absence of something, and in the semantic meaning it is always the absence of something concrete.
In the material world, this is the absence of matter, energy or space. In the spiritual realm, it is the absence of feelings, emotions, or aspirations.
Strange as it may seem, cosmic void has tremendous power, dark energy and dark matter are hidden in it. Not for nothing, according to the Big Bang theory, our universe came from the void.
So the psychic emptiness is endowed with invisible energy and just waiting for the moment to pour forth streams of new vitality!
Not for nothing they say that if you look for a long time into the Abyss (Emptiness), then the Abyss begins to look at you.
