— Ta-an (d. 883)
Each of you has a priceless jewel in your own body. It radiates light through your eyes, shining through the mountains, rivers, and earth. It radiates light through your ears, taking in all sounds, good and bad. It radiates light through your six senses day and night. This is also called absorption in light. You yourself do not recognize it, but it is in your physical body, supporting it inside and out, not letting it tip over. Even if you are carrying a double load of rocks over a single-log bridge, it still doesn’t let you fall over. What is this? If you seek in the slightest, then it cannot by seen.
