The Buddha told the wanderer, “I explain the truth of suffering … formation of suffering … cessation of suffering … the truth of the escape from suffering. Why is that? They are compatible with meaning and with the teaching, and they are the leaders of the religious life, dispassion, the unconditioned, cessation, calming, right awakening, the ascetic, and Nirvāṇa. This is why I explain them.”
