A mystic gives to purity its natural meaning. Pure water means that nothing is mixed with the water, that there is no other element in it, and therefore purity is that substance within oneself which is pure. As soon as this substance is realized one finds that all qualities such as good or bad, right or wrong, exist outside purity, since there is no goodness which is not touched by what may be called evil, nor is there any evil which has no touch of goodness. There is no wrong which has no right side to it, and there is no right which has not got a wrong side to it. Therefore as one comes to realize this purity one becomes reluctant to express an opinion about anything or anybody. It is always the foolish who are readiest to express their opinion about others; the wiser the person the less inclined he feels to form an opinion of anyone else. If he has to say anything about someone it is only good. Besides, no one who has once realized this purity tries to force his belief or his opinion upon another, because as soon as the purity which is within is realized, he no longer has an opinion which can be expressed in words.
