Neither the stone that made you stumble is your enemy, nor the stone that helped you cross the river is your friend! Universe just lives its own life!

Seek not a lighthouse greater than the human mind! Believe not the existence of an emotion nobler than the compassion!

In youth, the greatest success is to see the world from the eyes of the aged people and to feel exactly how they feel.

Birds needs trees and mankind needs both of them! Protecting the nature and environment is not only a matter of ethics but also a matter of existence.

Mankind has one great habit, a bad habit: To create rules on behalf of God! Unless A God appears on the sky and says 'Here are the rules,' do not take any rule serious! Remember that in this universe, there is no port that you can take refuge apart from the reason and the science!

All the world is believers! They just believe in different absurdities!

The Earth loves us through its gravity and this love is ideal: It neither sticks to us nor let us to fly to the unknown darkness!
