I believe we are still so innocent. The species are still so innocent that a person who is apt to be murdered believes that the murderer, just before he puts the final wrench on his throat, will have enough compassion to give him one sweet cup of water.
Since we desire the true happiness that is brought about by a calm mind, and such peace of mind arises only from having a compassionate attitude, we need to make a concerted effort to develop compassion.
When a man says I cannot, he has made a suggestion to himself. He has weakened his power of accomplishing that which otherwise would have been accomplished.
