If the Buddha were only to have spoken about how cyclic existence is characterised by little happiness and a lot of suffering, without providing us a path for transcending this suffering, then the Buddhist approach could be seen as very pessimistic. But this isn’t the case. Buddhism first challenges us to appreciate and to come to a proper understanding of the suffering of samsara and then, after arriving at that appreciation, the Buddhist tradition then provides us with the means for going beyond it. This is the essence of renunciation.
