Buddha was a Soul Traveler

Quite by accident one day I came upon the writings of Guatama Buddha and him talking about how many planets had civilizations upon them. Now, it is important to realize that the way he speaks is not really to use the word planet, because that might not have even been a concept in his time. However, he does use the word "Worlds" to describe almost countless "Worlds" with trillions and trillions of beings upon them. He mentions that it is important for aspiring Buddhas to somehow go to these "Worlds" to minister to those there and to teach them of compassion and kindness and right mindful wisdom. So it is expected of Buddhas of the thousands to millions or more of worlds just in our galaxy to be visited by Buddhas of Earth and for Buddhas from other worlds to come to earth and to minister here as well. I was pretty amazed when I read all this, especially because the way he talks about it is not the way we think about such things today. So in reading an English translation one must not only wade through the translation but the totally different way of thinking about this when he lived over 2500 years ago in India and Nepal.
