Quote from : Buddha: A Story of Enlightenment Book

Asita wasn’t hungry this day, however. There were other ways to keep the prana, or life current, going. If he did visit the demon loka, it would take enormous prana to sustain his body. There would be no air for his lungs to breathe among the demons. He allowed the brilliant Himalayan sun to dry his body as he walked above the tree line. Demons do not literally live on moun-taintops, but Asita had learned special powers that allowed him to penetrate the subtle world. He had to get as far away as possible from human beings to exercise these abilities. The atmosphere was dense around population. In Asita’s eyes a quiet village was a seething cauldron of emotions; every person—except only small infants—was immersed in a fog of confusion, a dense blanket of fears, wishes, memories, fantasy, and longing. This fog was so thick that the mind could barely pierce it.
