Question: What is Mouna (silence)?

Sri Ramana Maharshi: That state which transcends speech and thought is mouna. That which is, is mouna. How can mouna be explained in words?

Sages say that the state in which the thought "I" (the ego) does not rise even in the least, alone is Self (swarupa) which is silence (mouna). That silent Self alone is God; Self alone is the jiva (individual soul). Self alone is this ancient world.

All other kinds of knowledge are only petty and trivial knowledge; the experience of silence alone is the real and perfect knowledge. Know that the many objective differences are not real but are mere superimpositions on Self, which is the form of true knowledge.
