It appears from this description that there is regular interplanetary travel between the planets of the demigods. Another significant point is that there is a planet covered mostly by great mountains, one of which is GandhamÄdana Hill. Three great personalities — Priyavrata, NÄrada and SvÄyambhuva Manu — were sitting on this hill. According to BrahmÄ-saá¹hitÄ, each universe is filled with different planetary systems, and every system has a unique opulence. For example, on Siddhaloka all the residents are very advanced in the powers of mystic yoga. They can fly from one planet to another without airplanes or other flying machines. Similarly, the residents of Gandharvaloka are expert in musical science, and those on SÄdhyaloka are all great saints. The interplanetary system undoubtedly exists, and residents of different planets may go from one to another. On this earth, however, we have not invented any machine that can go directly from one planet to another, although an unsuccessful attempt has been made to go directly to the moon.
