Joan Borysenko says…

Meditation is a form of mental martial arts.  If we resist thoughts, they will overpower us.  But if we just step lightly out of their way, letting them come and go like birds flying overhead, we can use their energy to further focus our minds.

The nature of the mind is to think and create, so the mind naturally wanders during meditation.  The demoralizing thought that only your mind wanders while other meditators are sitting there in bliss is a major reason why people give up on meditation practice.  All people think when they meditate.  What distinguishes the novice from the skillful meditator is the attitude of detached awareness that the skillful meditator maintains toward thinking.

Is this true for you?  How do you handle it when your mind is restless?
