Believe nothing just because a so-called wise person said it. Believe nothing just because a belief is generally held. Believe nothing just because it is said in ancient books. Believe nothing just because it is said to be of divine origin. Believe nothing just because someone else believes it. Believe only what you yourself test and judge to be true.
Noble and wise men once believed in the music of the spheres: noble and wise men still continue to believe in the "moral significance of existence." But one day even this sphere-music will no longer be audible to them! They will wake up and take note that their ears were dreaming.
Thou hast a voice, great Mountain, to repeal. Large codes of fraud and woe; not understood by all, but which the wise, and great, and good interpret, or make felt, or deeply feel.

We live in succession, in division, in parts, in particles. Meantime within man is the soul of the whole; the wise silence; the universal beauty, to which every part and particle is equally related; the eternal ONE.
The wise man does not expose himself needlessly to danger, since there are few things for which he cares sufficiently; but he is willing, in great crises, to give even his life - knowing that under certain conditions it is not worthwhile to live.
