The way we are led out of cyclic existence involves the Buddha’s fundamental teaching of the Four Noble Truths, which entails cessation of the causes of suffering. Soon after his enlightenment the Buddha first presented this teaching in Varanasi. He taught the Noble Truth of Suffering, the Noble Truth of its Cause, the Noble Truth of Cessation and the Noble Truth of the Path. He explained that suffering must be known, its cause must be abandoned, cessation must be actualised and the path cultivated. However, once suffering is known there is nothing to be known, nothing to be abandoned, nothing to be actualised and nothing to be cultivated.
