Many people have clever speech, but only clever speech is not enough. Only cognition, without practicing, is dry cognition. Without both correct meditation and correct cognition, yon cannot find your true self. When not-moving mind and understanding come together, this is Zen. This is clear mind, not dependent on feeling or words, not dependent on anything.
Clear mind means keeping a mind that is clear like space, clear like a mirror.
