Patriotism cannot be our final spiritual shelter; my refuge is humanity. I will not buy glass for the price of diamonds, and I will never allow patriotism to triumph over humanity as long as I live.
The fish in the water is silent, the animals on the earth is noisy, the bird in the air is singing. But man has in him the silence of the sea, the noise of the earth and the music of the air.
I thought that my voyage had come to its end at the last limit of my power, that the path before me was closed, that provisions were exhausted, and the time come to take shelter in a silent obscurity, but I find that thy will knows no end in me, and when old words die out on the tongue, new melodies break forth from the heart, and where the old tracks are lost, new country is revealed with its wonders.
A teacher can never truly teach unless he is still learning himself. A lamp can never light another lamp unless it continues to burn its own flame. The teacher who has come to the end of his subject, who has no living traffic with his knowledge but merely repeats his lesson to his students, can only load their minds, he cannot quicken them.
