Those ignoramuses who think that birds are happy in their cages know not a single thing about freedom!

Every time a strong wind blows, every sand and dust yearns for being a solid rock and every solid rock longs for flying with the wind!

Not every New Year will be new unless we do something new!

New ideas seem like frightening ghosts to people at the beginning; they run away from them for a long time, but they get tired of it in the end!

Are you a sheep? Do you want to get rid of your shepherd? I say forget it till you develop wild teeth and grow paw; and until then, enjoy the sound of flageolet!

We wonder of the nature and the nature wonders of us!

Man! What are you? Who are you? Just a shadow in this universe! You always forget this and the truth will always remind you what you really are! Do you want to be a real thing, not just a shadow? Improve your science ten thousand times; improve your science hundred thousand times! If you can't improve your science, you will remain as a miserable shadow!
