The gross materialists do not believe in the existence of God or the demigods. Nor do they believe that different planets are dominated by different demigods. They are creating a great commotion about reaching the closest celestial body, Candraloka, or the Moon, but even after much mechanical research they have only very scanty information of this Moon, and in spite of much false advertisement for selling land on the Moon, the puffed-up scientists or gross materialists cannot live there, and what to speak of reaching the other planets, which they are unable even to count.
