Maitreya, the Buddha has prophesied that only one more birth stands between you and unexcelled, perfect enlightenment. What kind of birth does this prophecy concern, Maitreya? Is it past? Is it future? Or is it present? If it is a past birth, it is already finished. If it is a future birth, it will never arrive. If it is a present birth, it does not abide. For the Buddha has declared, “[Monks and nuns], in a single moment, you are born, you age, you die, you transmigrate, and you are reborn.”
