It is the activity of the intellect that constitutes complete human happiness - provided it be granted a complete span of life, for nothing that belongs to happiness can be incomplete.
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.
The gospel of cheerfulness, I had almost said the gospel of amusement, is preached by people who lack experience to people who lack vitality. There is a vague impression that the world would be a good world if it were only happy, that it would be happy if it were amused, and that it would be amused if plenty of artificial recreation - that recreation for which we are now told every community stands responsible - were provided for its entertainment.
Happiness of any given life is to be measured, not by its joys and pleasures, but by the extent to which it has been free from suffering-from positive evil.
It is in everybody's interest to seek those [actions] that lead to happiness and avoid those which lead to suffering. And because our interests are inextricably linked, we are compelled to accept ethics as the indispensable interface between my desire to be happy and yours.
Meditation is not the pursuit of pleasure and the search for happiness. Meditation, on the contrary, is a state of mind in which there is no concept or formula, and therefore total freedom. It is only to such a mind that this bliss comes unsought and uninvited. Once it is there, though you may live in the world with all its noise, pleasure and brutality, they will not touch that mind.
