Human evolution has got nothing to do with Self-realization. When you realize the Self you will know that there has never been any evolution, that there has never been any creation, that there are no Gods, no demons, no animals, and not even any people. All these things belong to the mind, to the ego. They are all ignorance.
You think 'I am so and so, he is so and so.' This is just ignorance. It is a cycle that has no ending. But once you have true realization, you know that you were never born. Some desire from the past has appeared in a physical form. It has manifested as this specific person. But in reality, nothing has happened. This is the ultimate truth.
