A very important point in the Rosicrucian teaching is that in which we are informed that the evolution of man is not confined to this planet, the earth, but rather is extended to a chain of seven planets. The Rosicrucians teach that the evolutionary processes of this planet are linked with and blended into the evolutionary processes of six other planets; and that life on this planet is likewise linked with and blended into the life on the six other planets of our planetary chain.
The Rosicrucians teach that these seven planets of our planetary chain are closely linked and connected by subtle etheric forces, and that there is a constant etheric current passing from one to the others and flowing ever through the entire circuit. These connected planets constitute the chain of worlds which is the series of homes of the individual soul, and the circuit of which is travelled by all individual souls.
Not only does each individual soul now on earth reincarnate a number of times on this planet, but in the course of the ages it progresses to the next highest planet, just as in ages past it has progressed from the next lowest one. And this round of the chain of planets has been made several times by the human race in some form of existence, and will be made again several times.
