Now, once on a time, the gods, while performing sacrifice, were afraid of an attack from the Asura-Rakshas. They perceived that prayer for a safe journey; and having warded off the evil spirits by means of that prayer, they attained wellbeing in the safe and foeless shelter of that prayer. And so does he now ward off the evil spirits by means of that prayer, and attain wellbeing in the safe and foeless shelter of that prayer. For this reason he says, 'We have entered upon the path that leadeth to well-being, free from danger; whereon he escheweth all haters and meeteth with good.'
