All states that can be returned to external causes are obviously not you, but that which cannot be returned to anywhere, if it is not you, what is it? Therefore, you should know that your mind is fundamentally wonderful, bright, and pure and that because of your involvement with the things of the world you have covered it up and lost it. In this way you are caught on the endless wheel of becoming this or that, sinking and floating in that sea of endless becoming. Awaken yourself now to your own bright mind.
