It is always a great honour to mention a truth which has not become widespread yet. One of these truths is that man has no soul; he has only 'body' and 'mind'. Man's unshakable belief on the soul will not change this scientific truth! No belief can be higher than the scientific truths! Man can be born, can walk and work and can think without owning a mysterious and an immaterial soul! The soullessness of the man is a great tragedy both for the man and for the religion. But Man, contrary to the religion, will come out with triumph from this tragedy.

Be clever and do not build walls, because in the future they will bring only shame to you!

There is a beauty in every hell!

Man is a culture, nothing but a culture! Question your culture! Just like monkeys picking lice from their skin, get rid of the stupidities in your culture!

The wisdom of the Moon is greater than the wisdom of the Earth, because the Moon sees the universe better than the Earth can see it!

Only when you give up being consistent will you find the truth! Inconsistency makes you free to discover other roads.
