The Stories of the Lotus Sutra, p4-5All of these stories [of the Lotus Sutra] essentially say to the hearer or reader, “you too.”
If shravakas and evil monks and little girls can become buddhas, so can you. And the teaching that buddha-nature is universal, a teaching not explicitly presented but strongly implied in the Lotus Sutra, does the same thing. It basically says that there are no exceptions to having buddha-nature; therefore you cannot make an exception of yourself.
That, I think, is the core purpose of the Lotus Sutra, not merely the abstract notion of universal awakening, but the always-present possibility and power of awakening, which is a kind of flowering, in each one of us.
The Buddha says to Shariputra in Chapter 3 of the Lotus Sutra, “Did I not tell you before that when the buddhas, the world-honored ones, by using causal explanations, parables, and other kinds of expression, teach the Dharma by skillful means, it is all for the purpose of supreme awakening? All these teachings are for the purpose of transforming people into bodhisattvas.” (LS 112)
These stories, then, are instruments, skillful means, to help us see and embrace what we might not otherwise see or appreciate – the potential and power in each of us to take up the way of the bodhisattva, which is to become supremely awakened, which is to become a buddha.
