The teachings of Buddhism are as varied as the denominations and interpretations of Christianity.

According to the Japanese Buddhist reformer, Nichiren, the culmination of Buddha's teachings is found in the Lotus
Sutra... the essence of which teaches the fundamental enlightened state of all beings.
According to Nichiren Buddhism, all of the benefits and wisdom of the Lotus Sutra are contained in the mantra Nam Myoho Renge Kyo. Try chanting it for five minutes and see what happens.
