Buddhism differs distinctively from other religions. Though all have fine teachings, there is no clear evidence of another case in which the founder of a religion attained his own supreme enlightenment and established his own religion. Some religions proclaim that their founders were sent by God. Others declare that God gave a revelation to the founder or that God descended from heaven to this world.

Unlike these religions, the teaching of Buddhism is the truth that Lord Sakyamuni, who was born as a human being like all of us and experienced human suffering and worry, aspired to enlightenment, practiced ascetic disciplines, and attained enlightenment after six years of spiritual effort. The process through which he attained his enlightenment can be clearly seen. Therefore, we can feel confident that we are sure to reach supreme enlightenment eventually if only we follow the Buddha’s teachings and traverse the same path. It is also sure that because this teaching is one that sprang up out of the earth (actual life), we who actually live in this world can follow it. Chapter 15 makes this point emphatically.
