There have been great people whose living thoughts could make anyone live; they could impart life and heal. They have left their thoughts behind them, and people have treasured them as scriptures, as holy books; they have taken them for a religion. Such thoughts can never vanish nor die, such a long life has been given to them. Whatever form their thoughts have taken, whether music, prose, poetry, aphorisms or precious sayings that will never die, they will live for ever. There are others who have not known the value nor the immortal character of this creation of the mind; they pass through life without realizing its value. Such persons are foolish, stupid, grumbling all the time about people, and criticizing others.
