“Happiness does not lie in happiness, but in the achievement of it.”

“If they knew that they are happy, they would be happy.”

“For men are made for happiness, and any one who is completely happy has a right to say to himself, ‘I am doing God's will on earth.’ All the righteous, all the saints, all the holy martyrs were happy.”

“Men are made for happiness, and he who is completely happy has the right to say to himself, 'I am doing God's will on earth.”

“The greatest happiness is to know the source of unhappiness.”

“This is my last message to you: in sorrow, seek happiness.”

“It is better to be unhappy and know the worst, than to be happy in a fool's paradise.”
