9th century Zen master, Tozan Ryokai, attained enlightenment many times. Once when he was crossing a river he saw himself reflected in the water and composed a verse, “Don’t try to figure out who you are. If you figure out who you are, what you understand will be far away from you. You will have just an image of yourself.”
Actually, you are in the river. You may say that is just a shadow or a reflection of yourself, but if you look carefully with warm-hearted feeling, that is you. You may think you are very warm-hearted, but when you try to understand how warm, you cannot actually measure. Yet when you see yourself with a warm feeling in the mirror or the water, that is actually you. And whatever you do, you are there.
