You can even prove to yourself what Nature's requirements are for getting out of this prison. It's called "The Holy Trinity:" the Father, Son, and Holy Ghost. Here's a description as follows:
1. The Father: knowledge (Math, Physics, Astronomy, Languages, Biology, or whateger).
2. The Son: Ethics and Morals. We are the children of our thoughts and learning. There are lots of things we do incorrectly. Disobeying the Ten Commandments is not the whole picture. For example, we don't even know how to control the common cold yet. I could go on and on.
3. The Holy Ghost. The Holy Ghost is just each person's spirit. Yes, the kind that people think wails "woo-woo" in the night. The ancients said: "As above, so below." The Buddhist Book of the Dead tells us that when a spirit separates itself from the physical body, it enters the Void thinking and believing exactly as it did in the physical realm. If it was a Jehovah's Witness, it'll do its best to get the other spirits to read their poorly printed little spirit magazines. If it was a Moslem, it will try to lop off all infidels' heads with a spirit sword. (Thank God for that. Such sword cuts are not too painful.) If it is a skeptical atheist, it will call the other "true believing" spirits "unscientific" and "superstitious." Little by little, as the previous ego begins to dissipate, the spirit sees that not all the "rules" it learned in the physical world apply to the Void. When it realizes that it is now in the spirit dimension, it returns to the physical realm for another try. It keeps this up until the Physical Realm and the Void become completely unified in Truth.
Rob, what pressures are humans under all the time? Are they not pressures to educate ourselves, improve ourselves morally, and accept the reality of a spirit dimension? This "Holy Trinity" will hound us for as many millenniums necessary for us to do what we must do in order to get out of this jail forever.
