When the Buddha attained enlightenment he clearly knew all dhammas as they really are. He taught the “Dhamma”, the teaching on realities, to us in order that we also may know dhammas as they are. Without the Buddha’s teaching we would be ignorant of reality. We are inclined to take for permanent what is impermanent, for pleasant what is sorrowful and unsatisfactory (dukkha), and for “self” what is non-self. The aim of all three parts of the Tipitaka is to teach people the development of the way leading to the end of defilements.
