Winter always turns to spring.

Those who believe in the Lotus Sutra are as if in winter, but winter always turns to spring. Never, from ancient times on, has anyone heard or seen of winter turning back to autumn. Nor have we ever heard of a believer in the Lotus Sutra who turned into an ordinary person. The sutra reads, "If there are those who hear the Law, then not a one will fail to attain Buddhahood."-Nichiren
