Conversion of the Actual World Into An Ideal Realm

The idea that meditation or self-destruction through asceticism frees a spirit after the death of the body posits the existence somewhere of a spirit world. Once again, the general Buddhist view is that even if it exists, such a spirit world has no relation to the ordinary world of human experience. The goal of Buddhism is not the attainment of a fictitious paradise but the conversion of the actual world into an ideal realm—a Buddha Land. In practice, believers in meditation and asceticism as ways to nirvana are usually seeking personal escape from this life. They may achieve their end, but true happiness is not to be gained by self-centered means. It can be realized only when all humankind has reached a state of peace and happiness.
