Name some Buddhist mantras?

"We are all much more than we know. We are all Buddha. But we live by illusions and only see through our senses. So we cannot know how much we are. No one can know himself; therefore people will live behind many masks, and call themselves by many names. When all that matters is the effect we have on others. Thus, even a monster may want to be kind, friendly and gentle. And what is more friendly than a puppy dog."
