Your past is always useful to you: If you are happy with your past, you get power from it; if you are unhappy with your past, you take lesson from it!

Truth wanders everywhere, but especially and frequently, it wanders in the silence. To meet with it, you wander in the silence too.

Minutes without seconds and hours without minutes cannot exist! Respect the links before respecting the chain!

While other creatures of the evolution are just watching the universe, man alone has the power to change the fate of the universe.

Freeze, freeze in the winter, if you really want to appreciate the summer! Walk, walk at the edge of the precipices, if you rightly want to learn the meaning of the safety! Switch the lights off, if you want to see the amazing beauty of the light!

Starting from the primary schools, there must be compulsory 'Cosmos' classes throughout the education period. If a man thinks about and understands the universe, he will have wider horizons; he will be much less conceited and much more realistic.

You have so many miles and so many years to reach the stars; if you ignore this, you can reach over there!
