We are ceasing being creative, when we imitate, when we as natural beings only reacts on the bases of memories.
Answers from the memory are usually called thinking. But such thinking is only reactions from those preconceived conceptions, which are memory. It is only a reaction in the brain and not real thinking.
There is only real thinking, when there isn´t any reaction from the memory.
In this awake and passionate emptiness there is creation.
And when you are in this condition all stimuli and demands of life vanish.
