Tell us about the principles of psychological training, but tsuki no kokoro mitsu no kokoro and others that you know.
Thank you for your post and sorry for the delay of my reply.
I am not too sure what you are asking. You probably read some books of zen.
I am sure that tsuki no kokoro is the state of your mind is as clear as the moon, which means you have reached enlightenment.
I have no idea what mitsu no kokoro is. If I do not heard of it, I have to guess. But to guess, I have to see Japanese characters.
Sorry that I cannot be a help for this
