“The tragedy of man is that the happy moments of life behave like the birds of the forests: They appear and disappear suddenly!”

“The nonpermanent appearance of happiness and distress, and their disappearance in due course, are like the appearance and disappearance of winter and summer seasons.They arise from sense perception,and one must learn to tolerate them without being disturbed.”

“Man's life seems to me like a long, weary night that would be intolerable if there were not occasionally flashes of light, the sudden brightness of which is so comforting and wonderful, that the moments of their appearance cancel out and justify the years of darkness.”

“It wasn't the disappearance of happiness so much as the appearance of sadness.”

“Here is the fate of the man: To appear and to disappear!”

“Once more I realized to what an extent earthly happiness is made to the measure of man. It is not a rare bird which we must pursue at one moment in heaven, at the next in our minds. Happiness is a domestic bird found in our own courtyards.”
