Your travel on the road to truth starts with daring to suspect your own believes!

Man must spend much more time in extraordinary natural places to grasp much better how remarkable our planet is and to realise what a great privilege and what an enormous joy to be living here!

Universe is blind; it cannot see us; we must find a way to show ourselves to it and science is the way to open the eyes of the universe!

In peace, continue your art; in war, continue your art; in freedom, continue your art; in captivity, continue your art!

Where the sun sets, love rises!

On the road to your target, move cleverly and silently; when you reached your target, be humble and silent!

Beautiful roads do not always lead to beautiful places! Heaven may be hidden at the end of an ugly road! Do not be deceived by the beginning; try to see the end!
