The Purpose of Oneself (Buddha) is Love.

It is not that there is no self, it is that there is only oneself which appears (to itself) as many separate selves so not to be by itself. What it means is that (the purpose of) self - the meaning of life in all its diversity - is love. Hence the gospel of love. As to Energy; the E=mc2 equation is synonymous with I=mc2. E=I and I=E. But best to go full-circle on Oneself. Full circle is realizing One's purpose is Love.
