What Is the All?

How do we relate to the basic building blocks of experience that then go on to construct our lived reality? There's one short discourse that the buddha gave which is so simple and so radically profound. He describes, in six short phrases, the all, the totality of our experience. So what is the all? And again, just as a side note, even though during these talks i'm going to be using the pronouns of i and you and me and we and they, keep in mind that itre ts some essential ho behind it all.
