How selfish soever man may be supposed, there are evidently some principles in his nature, which interest him in the fortune of others, and render their happiness necessary to him, though he derives nothing from it, except the pleasure of seeing it.
Now if there is any gift of the gods to men, it is reasonable that happiness should be god-given, and most surely god-given of all human things inasmuch as it is the best. But this question would perhaps be more appropriate to another inquiry; happiness seems, however, even if it is not god-sent but comes as a result of virtue and some process of learning and training, to be among the most god-like things; for that which is the prize and end of virtue seems to be the best thing in the world, and something god-like and blessed.
Happiness is a state of mind. With physical comforts if your mind is still in a state of confusion and agitation, it is not happiness. Happiness means calmness of mind.
All places that the eye of heaven visits Are to a wise man ports and happy havens. Teach thy necessity to reason thus; There is no virtue like necessity.
Happiness is one pole, sadness is another. Blissfulness is one pole, misery is another. Life consists of both, and life is richer because of both. A life only of blissfulness will have extension, but will not have depth. A life of only sadness will have depth, but will not have extension.
False happiness is like false money; it passes for a time as well as the true, and serves some ordinary occasions; but when it is brought to the touch, we find the lightness and alloy, and feel the loss.
The most venerable, clearly understood, enlightened, and reliable constant in the world is not only that we want to be happy, but that we want only to be so. Our very nature requires it of us.
You will have many enemies, but even your foes will love you. Life will bring you many misfortunes, but you will find your happiness in them, and will bless life and will make others bless it-which is what matters most.
