A rich man, if he is displeased with his servant and speaks roughly to him or insults him, may not realize it at the time, but perhaps the feeling of this servant who is dependent on him and who is bound to that particular place is hurt. And when this rich man goes to his office, to his affairs, he may get back that pinprick which he gave. He does not know it; he believes he has given a pinprick to a servant who could not return it; but someone else returns it without his realizing that this is the answer to what he has done. The more we think about this the more we shall understand how God works through all beings, even through animals and birds. And then when we are able to believe this, we cannot help believing what Buddha has said: that the essence of religion is harmlessness. Harmlessness does not only mean to refrain from killing. Many are killed without killing; in order to kill a person one does not need to murder him. A glance, a word, a thought can kill a person and that is worse than death.
