So, the Upanishadic teachings open and stimulate your intelligence. Be alive; look around. Look at the sky, look at the moon, look at the planets, and look at the stars on a beautiful, clear night sky. Look at the rivers as they flow. You know, this is why the rishis lived in those beautiful forests—deep in the woods with the snow-clad mountains overlooking them. Their minds moved with great veneration and ascended high levels of being because they were not conditioned either by their thinking or polluted in the body by environmental hazards of today.
We can do it even now—clean up the air, sit quietly and think with a clear mind. Not fall into a semi-hypnotic trance that usually results in a bout of snoring. That is called Sushupti. It’s not Samadhi, deep sleep. It is to be able to keep our minds open to receive, to forget the images that trouble us. To break through the conditioning imposed upon us by our past and by our environment. You know, the human body has evolved now up to the level of Homo sapiens. The brain has evolved, it can think, and it can even go to the moon.
