Mitsu means “secret,” or “mystical,” in the sense of not apparent to the senses or the intellect, but experienced directly or immediately — as if two things are touching. Go means “words” or “talk.” So mitsugo means “secret talk,” that is, something communicated directly without sound. In Buddhism it is said that there is secret talk that can be recognized and understood even though it has no sound. So “secret talk” suggests the existence of intuitive perception. It is a fact that we can sometimes discover meaning, or secrets, without receiving any external stimuli, but we need not see the fact as particularly mystical. An analogy that helps to understand such facts is the sympathetic resonance of tuning forks.
