"Our scientists assert that human life does not exist on such planets as Mars, Venus, Jupiter, etc. This assumption arises out of their ignorance of the etheric levels of matter. Their technology is still inadequate to measure the full range of the material planes. Had they etheric vision, they would know that all the planets of our system are inhabited and that many are far more advanced in evolution than we are on Earth. The time is fast approaching when a more open-minded view of life with its mysteries will supersede the arrogance of the ignorant, to the benefit of us all. (Preface)"
