A Tibetan Buddhist master meditates away his panic disorder

"If you tell panic, 'Get out, I don't like you,' then panic becomes your enemy and you cannot get rid of it. If you say, 'Yes, sir, panic, whatever you say is true,' then panic becomes your boss. The best method is to make friends with panic. Use panic in your meditation. Look at the panic, and use it as an object of mindfulness, of awareness."

Yongey Mingyur Rinpoche (profiled here) tells how he used his meditation practice to overcome panic.

Check out past PANIC! posts about meditation and panic, including this one in which I discuss having a panic attack in the middle of a meditation class.
