Thought is an expression of INNER FLOW, and thus the currents of thought meld and integrate into bigger and more profound amalgamations, and then..........................you summarize it into spoken or written forms, so you can share it without confusing the person recieving the thoughts.

The loudest and most profound voice is actually perfomed with silent actions.
