A Question About the Dimension of Nothingness
“They speak of this thing called the ‘dimension of nothingness’. What is the dimension of nothingness? It occurred to me: ‘It’s when a mendicant, going totally beyond the dimension of infinite consciousness, aware that “there is nothing at all”, enters and remains in the dimension of nothingness. This is called the dimension of nothingness.’ And so … I was entering and remaining in the dimension of nothingness. While I was in that meditation, perception and focus accompanied by the dimension of infinite consciousness beset me.
