The Mysteries of Yogic Powerr
Hṛdayānanda dāsa Goswami.  And are all the varieties of life we see on earth contained in the spiritual world?
Śrīla Prabhupāda.  Yes. And, moreover, if in this inferior energy there are so many wonderful varieties of life, just think how wonderful are the superior varieties of life in the spiritual world. Even in this material universe, the inhabitants of some planets are far superior to those on other planets. For example, people on earth practice mystic  yoga  for achieving wonderful powers, but people on the planet called Siddhaloka have these great yogic powers naturally. On earth it is natural that a bird can fly; but we cannot, except with costly machines. However, on such planets as Siddhaloka, the residents can fly even from one planet to another without machines. They can go to other planets simply at will. Even on earth there are some  yogīs  who can take their bath early in the morning in four places at once-Jagannātha Purī, Rāmeśvara, Hardwar and Dvārakā.[22] One  yogī  friend used to visit my father in Calcutta. The  yogī told  him that when he (the  yogī ) would simply sit down and touch his  guru , he would travel from Calcutta to Dvārakā in two minutes. That is yogic power. So what are today's airplanes? Durvāsā Muni traveled all over the universe and up to Vaikuṇṭha[23] within one year. According to modern calculations, certain planets in this universe are more than forty thousand light-years[24] distant from the earth. This means it would take forty thousand years to reach these planets if you traveled at the speed of light. Even if they had the means, how could the astronauts live for forty thousand years? So, why are they so proud?
Dr. Singh.  The scientists have a theory that they can produce a machine that will travel at the speed of light.
Śrīla Prabhupāda . That is rascaldom. They say that, but they will never be able to do it.
Vedic Cosmology
Śrīla Prabhupāda.  There are many invisible planets and stars. For example, when the Rāhu planet passes before the sun and moon, there is an eclipse. But the scientists describe an eclipse differently. Actually, the Rāhu planet causes an eclipse. There are many questionable points regarding the modern scientists' theory of the eclipse. Their explanation is incorrect according to Vedic information.
Dr. Singh.  But the scientists say that they can prove their theories.
Śrīla Prabhupāda.  They say that science proves everything. But that is nonsense. The scientist has proved everything except what he is.  That  he does not know. And why does he die? That also he does not know. That is the extent of his knowledge.
Dr. Singh.  They can make a model of the universe. They can make a model of the planets and the moon.
Śrīla Prabhupāda.  If they can make things, why don't they make an imitation sun to save electricity? These rascals say everything, but they cannot do anything. That is their position. If they can make a model of the universe, let them make a big model of the sun. Then in the dark night we will not have to spend so much money on electricity. But they cannot do it. Yet they speak big, big words, simply to take money from the taxpayers. They say they know the composition of the moon and the composition of the sun, so why can't they make them? Why can't they create an artificial sun so that the people of Iceland and Greenland can be saved from so much cold?
