Experience of the void

A student of Mr. Ouspensky and Mr. Gurdjieff
later met an Indian teacher, who expressed a concept
that Mr. Ouspensky did not put into his books.
Mr. Ouspensky described the multitude of thoughts
that we experience, by working to be aware, may gradually
become one unified and controlling faculty.
(Mastery of the self). The teacher said, beyond
this there are two more states: When you have
achieved mastery, the next stage is the sense
of one's nothingness, then the next stage will
be the experience of the Void.
