Because the whole world is a complex web of relationship, we are always in relationship.
Because the sun shines, we have chocolate to eat. Because your grandparents' parents met, you are here. We are in relationship with ourselves, with each other, with the world. This is called dependent origination:
"This being- that becomes. From the arising of this, that arises. This not being, that becomes not. From the cessation of this, that ceases."
Majjhima Nikaya II.32
You are not separate from all of life, from this world - you are life itself. We are all a co-arising miracle with the same beauty and mystery as a flower or the vast night sky filled with stars.
