"The demon who appeared to test the boy Snow Mountains was actually Shakra. The dove saved by King Shibi was the heavenly king Vaishravana. It is even possible that the ten demon daughters have possessed your parents and are tormenting you in order to test your faith. Any weakness in faith will be a cause for regret. The cart that overturns on the road ahead is a warning to the one behind. In an age like this no one can help but thirst for the way. You may hate this world, but you cannot escape it."
