Buddha

A fool acquires knowledge only to his own disadvantage. It destroys what good he has, and turns his brains.

Everything changes, nothing remains without change.

Those... who find delight in freedom from attachment in the renunciation of clinging, free from the inflow of thoughts, they are like shining lights, having reached final liberation in the world.

When a man venerates those worthy of veneration, be they Buddhas or their disciples, who have transcended all obstacles and passed beyond sorrow and tears - venerating such as these, whose passions are extinguished and for whom there is no further source for fear, no one can calculate how great his merit is.

Give up pride.

One may desire a spurious respect and precedence among one's fellow monks, and the veneration of outsiders. "Both monks and laity should think it was my doing. They should accept my authority in all matters great or small." This is a fool's way of thinking. His self-seeking and conceit just increase. One way leads to acquisition, the other leads to nirvana. Realizing this a monk, as a disciple of the Buddha, should take no pleasure in the respect of others, but should devote himself to solitude.

Dispassion is the best of mental states. . . .

Suffering does not befall him who is without attachment to names and forms. 

The good renounce everything. The pure don't babble about sensual desires. Whether touched by pleasure or pain, the wise show no change of temper.

The wise say that it is not an iron, wooden or fiber fetter which is a strong one, but the besotted hankering after trinkets, children and wives, that, say the wise, is the strong fetter. It drags one down, and loose as it feels, it is hard to break. Breaking this fetter, people renounce the world, free from longing and abandoning sensuality.
