'In another time, long before the Empire, and before the Republic had been formed, a holy man called the Skywalker became aware of a powerful energy field which he believed influenced the destiny of all living creatures...after much study, he was able to know the force, and it communicated with him. He came to see things in a new way. His 'aura' and powers grew very strong. The Skywalker brought a new life to the people of his system, and became one of the founders of the Republic Galactic…As you know, the 'FORCE OF OTHERS' has two halves: Ashla, the good, and Bogan, the paraforce or evil part. Fortunately, Skywalker came to know the good half and was able to resist the paraforce; but he realized that if he taught others the way of the Ashla, some, with less strength, might come to know Bogan, the dark side, and bring un- thinkable suffering to the Universe. For this reason, the Skywalker entrusted the secret of THE FORCE only to his twelve children, and they in turn passed on the knowledge only to their children, who became known as the Jedi Bendu of the Ashla: 'the servants of the force'. For thousands of years, they brought peace and justice to the galaxy. At one time there were several hundred Jedi families, but now there are only two or three.'
When George Lucas talks about the prequels being closer to his "original vision", he might just be right.
