Everything in this world is naturally knowledge-driven. This is how development takes place. Knowledge comes and everything follows this new path. Man is also driven by knowledge. The realization and the following development comes by itself. So that the realization can come and the development can take place it needs the free flow. This is opposed by the human mind. The free flow becomes a narrow rivulet, set in concrete and determined in its course, within the narrow limits of the ego. This rivulet, in turn, the ego itself then considers to be knowledge. The kind of development that follows such cognition (according to cause and effect) we see every day.
