Answer: The world is managed by one force called the Creator or nature. No one else can manage creation. However, the more a person resembles this force, the more he can contribute to making our world a better place, because he thus becomes a transmitter of the upper force into our world.
Question: Is there any evidence?
Answer: A person will have proof only when he attains the level on which he begins to feel that by his positive impact on our world, it really affects him, and this is proof he actually influences the world.
