Brain scientists and Buddhists claim that the sense of self, the ego, is an illusion. But isn't the world itself an illusion? Isn't the world as we know it created in the brain? Your eyes detect light waves and convert them into nerve impulses that are transported to the brain, where, voila, an edited video is formed. But this is not the reality—it's just an edited tiny fraction of it. As Kant said, what you experience is not the reality itself but the reality for you.
What would the world look like if no one was there who could perceive it? More than 99% of an atom consists of space between the nucleus and the electrons. According to the physicists, "the real world" is an endless empty space with a few elementary particles here and there bouncing about.
Are synchronicities, ESP, and miracles real, or are they delusions? Isn't everything a miracle? The more you learn about life and how a living cell and living organisms are constructed, the more astonished you will become.
So, you conclude there must be a superior intelligence behind it all, and you become religious. You become a Christian, a Muslim, a Hindu, or something New Agey. This is a mistake, I think. You don't need all the junk that comes with religion to be amazed and rapt by the great mystery.
