In tibetan philosophy, there is a symbol for knowledge and the loss of all illusions: the ritual knife "kartika". If we want to find a modern way of thinking, a expression of art, which fits to our time, we must use such a symbol knife in our thinking. Leave behind what seems safe and true. See it in a new way. See it with the knowledge, which is won by physics, cosmology and astronomy. We are little worms in an old apple, lying in a nowhere garden. What we can see and realise is not much. Our mind is in many ways imprisoned, bound and restricted. We cant even see half of the light waves which are emitted by an object. So, what do we see?
