“There is no greater power than that of a laugh and happiness is a force which can save a person from the horrors of the world.”

“As long as I can remember I feel I have had this great creative and spiritual force within me that is greater than faith, greater than ambition, greater than confidence, greater than determination, greater than vision. It is all these combined. My brain becomes magnetized with this dominating force which I hold in my hand.”

“Oh, oh, no greater evil is there in this world, than the evil that lies in the hearts of those who repay good with evil. Oh no greater shame be upon anyone in this world, than the shame that be upon the heads of those who will not save the life that saved them. No greater evil, no greater shame. No greater trespass against God and angel and man; than a human who can say that they are entitled to repay good with evil.”

“Can there be any happiness greater than the happiness of salvation?”

“There is a room in the Department of Mysteries, that is kept locked at all times. It contains a force that is at once more wonderful and more terrible than death, than human intelligence, than forces of nature. It is also, perhaps, the most mysterious of the many subjects for study that reside there. It is the power held within that room that you possess in such quantities and which Voldemort has not at all. That power took you to save Sirius tonight. That power also saved you from possession by Voldemort, because he could not bear to reside in a body so full of the force he detests. In the end, it mattered not that you could not close your mind. It was your heart that saved you.”

“There is an energy which springs from sickness and debility: it has a more powerful effect than the real, but, sadly, expires in an even greater infirmity.”
