Meditation is always perfect, so there is no need to correct anything. Since everything that arises is simply the play of the mind, there are no bad meditation sessions and no need to judge thoughts as good or evil. Therefore one should not sit down to meditate with various hopes and fears about the outcome–one just does it, with no self-conscious feeling of “I am meditating,” without effort, without strain, without attempting to control or force the mind, without trying to become peaceful.
