But I see nothing miraculous about it. Nothing makes one as healthy as happiness, and there is no greater happiness than making someone else happy.

We are happy when people/things conform and unhappy when they don't. People and events don't disappoint us, our models of reality do. It is my model of reality that determines my happiness or disappointments.

Alors, dans l'obscurité j'ai pleuré de bonheur.

İnsana mutluluk kadar sağlık katan bir şey yoktur ve en büyük mutluluk da bir başka insanı mutlu etmektir.

States of profound happiness, like all other forms of intoxication, are apt to befuddle the wits; intense enjoyment of the present always makes one forget the past.
