The yogi concentrated for a long time, but he could not find where Hui-ch'ung's mind was. Master Hui-ch'ung then rebuked the yogi. "Your powers are worthy of a little ghost. You can see into a mind when it is moving, but when the mind is still, you are lost. As to where I am, that is simple. Since my body is here, of course my mind is also here."

From the Ch'an perspective, what are considered supernormal powers are, in fact, little tricks. Ch'an speaks of the great supernormal powers. When birds fly through the air and men walk the earth, they leave behind traces of their passage which last for thousands of millions of eons. As we move through our lives, we leave shadows of ourselves behind us. People with great supernormal powers can follow these shadows backward, as if they were watching a film in reverse, and trace them through innumerable past lives. This is an example of a great supernormal power.

In the last line of verse, the phrase "one perfect light" refers to Buddha-nature, which is the same as the Dharma body. The Dharma body is not separate from the physical body. However, you cannot say that the Dharma body is the physical body and nothing more. When you experience enlightenment, you are one with the Dharma body, yet you are still in your physical body. When you experience the Dharma body, you transcend the boundaries of your limited, physical body. While the enlightenment experience lasts ─ and it may be as quick as a flash ─ you will see no distinction between inside and outside. There will be no attachment to self, and no vexation. But this is not an accurate description. If you really want to know, you will have to find the mani pearl and experience it yourself.
