Life is a place where it is necessary to move gently. Whether it be in thought, speech, or action, the rhythm must be controlled; the law of harmony must be observed in all that one does. One should know that even walking barefoot on thorns will not make one free from accusation: the thorns will accuse one of having trampled upon them. If living in this world is as delicate as that, can anyone say he has gained sufficient wisdom? Or can anyone think he can afford to live in this world without giving a thought to this problem?
