You can indeed be aware of your body, but you can also be aware of your mind - you can right now notice all the thoughts and ideas and images floating in front of the mind's inward eye. You can, in other words, experience your mind, be aware of your mind. And it's very important to experience your mind directly, cleanly, intensely, because only by bringing awareness to the mind can you begin to transcend the mind and be free of its limitations.
