The natural state of the mind is neither happiness nor unhappiness. When feeling enters the mind then happiness or unhappiness is born. If we have mindfulness then we know pleasant feeling as pleasant feeling. The mind which knows will not pick it up. Happiness is there but it’s ‘outside’ the mind, not buried within the mind. The mind simply knows it clearly.
If we separate unhappiness from the mind, does that mean there is no suffering, that we don’t experience it? Yes, we experience it, but we know mind as mind, feeling as feeling. We don’t cling to that feeling or carry it around.
The Buddha separated these things through knowledge. Did he have suffering? He knew the state of suffering but he didn’t cling to it, so we say that he cut suffering off. And there was happiness too, but he knew that happiness, if it’s not known, is like a poison. He didn’t hold it to be himself. Happiness was there through knowledge, but it didn’t exist in his mind. Thus we say that he separated happiness and unhappiness from his mind.
