Nothingness, the Void, Emptiness: An ultimate idea with many names in Hindu, Buddhist and Zen thought which is often confused with mere negation. It is best understood as no-thingness, meaning it is boundless with no center or circumference and beyond spatio-temporal location, the infinite bliss consciousness without division or object of it.
