"• How Can Buddhism Help Me?
Buddhism explains a purpose to life, it explains apparent injustice and inequality around the world, and it provides a code of practice or way of life that leads to true happiness."

Also AKAism explains this:
There is no general purpose for life, apparent injustice and inequality around the wold is because there is no meaning, no purpose, no goal, no rules.. merely the survival of the fittest, and even that is not a goal or purpose, just a result. There is no fucking code that leads to true happines.. well.. stay alive, dead ones won't feel a thing.
