"The oft-cited parable of the burning house tells of a father distraught as his children blithely play, unaware that the house is ablaze. Knowing of their respective predilections for playthings, he lures them from the inferno with the promise that he has a cart for each waiting outside, a deer-drawn cart for one, a goat-drawn cart for another, and so on. When they emerge from the conflagration, they find only one cart, a magnificent conveyance drawn by a great white ox, something that they had never even dreamed of. The burning house is samsara, the children are ignorant sentient beings, unaware of the dangers of their abode, the father is the Buddha, who lures them out of samsara with the teaching of a variety of vehicles. . . knowing that in fact there is but one vehicle, the buddha vehicle whereby all beings will be conveyed to unsurpassed enlightenment."
