The value of life is not measured by time, but by depth. 15. Human beings have been given a job, that is, spiritual growth. 16.

The cause of science is to serve the people. Life is not a kind of enjoying the east, but a very heavy job. An ideal book is the key to wisdom. A mind without wisdom is like a lantern without a candle. People are too used to maintaining order by force, so it is impossible to consider social organizations that are not suppressed. Pure and complete sorrow is as impossible as pure and complete joy. What successful teaching needs is not coercion, but stimulating students' desire. The ideal book is the key to wisdom.
