A woman who embraces the lion king of the Lotus Sutra never fears any of the beasts of hell or of the realms of hungry spirits and animals. All the offenses committed by a woman in her lifetime are like dry grass, and the single character myō of the Lotus Sutra is like a small spark. When a small spark is set to a large expanse of grass, not only the grass but also the big trees and large stones will all be consumed. Such is the power of the fire of wisdom in the single character myō. Not only will all offenses vanish, but they will become sources of benefit. This is what changing poison into amrita means.
