To overcome the obstacles preventing our gaining better rebirths, liberation from uncontrollably recurring rebirth and enlightenment, we need to develop confidence in the Buddha and his teachings – confidence based on reason. We need to be convinced that liberation and enlightenment are possible, that the Dharma is the true path to attain these goals and that we are all capable of achieving them. When we learn what the true obstacles are and what the methods are for ridding ourselves of them, we can then put all our effort into overcoming them.
