Man's nature is originally pure. It is by false thoughts that True Thusness is obscured. Our original nature is pure as long as it is free from false thoughts. If one does not realize that his own nature is originally pure and makes up his mind to look at purity, he is creating a false purity. Such purity has no objective existence. Hence we know that what is looked at is false. Purity has neither physical form nor character, but some people set up characters of purity and say that this is the object of our task. People who take this view hinder their own original nature and become bound by purity.
