There is [a] quality of ordinary mind, which is the interior of consciousness, the voices in the head, the shift of feeling and sensation. Yes, that’s it, the voice in your head that says, “I don’t have voices in my head.” That one. Ordinary means that there is no need to add or take away from what is going on in the mind. Each portion of life has the whole of life. There is nothing wrong with what is in the mind except the sense that something is wrong. In this way simplicity turns to a form of compassion. When there is no objection to the states of mind that arise—ordinary or painful or thick—then they have their moment and move along, like clouds in the trade winds. And there is no flaw in the thinker or in the moment that is taking place.
