Day 6 continues Chapter 3, A Parable
Having last time considered Śākyamuni’s skillful expedients, we consider who was attracted to the sheep cart, the deer cart and the bullock cart.
“Śāriputra! Those who have intelligence, who receive the Dharma by faith after hearing it from the Buddha, from the World Honored One, and who seek Nirvāṇa with strenuous efforts in order to get out of the triple world, are called Śrāvakas. They may be likened to the children who left the burning house in order to get the sheep-carts. Those who receive the Dharma by faith after hearing it from the Buddha, from the World-Honored One, who seek the self-originating wisdom with strenuous efforts, who wish to have good tranquility in seclusion, and who perfectly understand the causes of all things, are called Pratyekabuddhas. They may be likened to the children who left the burning house in order to get the deer-carts. Those who receive the Dharma by faith after hearing it from the Buddha, from the World-Honored One, who strenuously seek the knowledge of all things, the wisdom of the Buddha, the self-originating wisdom, the wisdom to be obtained without teachers, and the insight and powers and fearlessness of the Tathāgata, who give peace to innumerable living beings out of their compassion towards them, and who benefit gods and men, that is to say, who save all living beings, are called men of the Great Vehicle. Bodhisattvas are called Mahasattvas because they seek this vehicle. They may be likened to the children who left the burning house in order to get the bullock-carts.
The Introduction to the Lotus Sutra offers this on the Three Carts:
From the theoretical standpoint, [The Parable of the Burning House] explains the relationship between the Three Vehicles and the One Vehicle. The three toy carts – the sheep-cart, deer-cart, and bullock-cart – respectively represent the Sravaka-Vehicle of the “hearers,” the Pratyekabuddha-Vehicle of the “private Buddhas,” and the Bodhisattva-Vehicle of those who serve and enlighten others. The large white bullock cart which is given to each of the children symbolizes the One Buddha Vehicle. The rich man first offered his children three kinds of carts as expedients, but in the end he gave each of them an identical large white bullock-cart. Obviously the Buddha told this parable to illustrate that the One Vehicle is true and the three are mere expedients. The differences between the One Vehicle and the Three Vehicles, which were discussed theoretically in Chapter Two, are now explained in a graphic story that anyone can understand and remember.
