“The soul who had to sympathize with whole world was thus prepared that drop of that poison which always produces contempt, resentment and ill feeling against another was destroyed first. So many talk about purification of heart, and so few really know what it is. Some say to be pure means to be free from all evil thought, but there is no evil thought. Call it evil or call it devil, if there is any such thought it is thought of bitterness against another. No one with sense and understanding would like to retain a single drop of poison in his body. And how ignorant it is on part of man when he keeps and cherishes a bitter thought against another in his heart. If a drop of poison can cause death of body, it is equal to a thousand deaths when heart retains smallest thought of bitterness." (56)
