He ( Lord Buddha ) was the only man who was ever ready to give up his life for animals to stop a sacrifice. He once said to a king, "If the sacrifice of a lamb helps you to go to heaven, sacrificing a man will help you better; so sacrifice me." The king was astonished. And yet this man was without any motive power. He stands as the perfection of the active type, and the very height to which he attained shows that through the power of work we can also attain to the highest spirituality.
