What gave rise to material existence?

What gave rise to material existence? What was the movement into creation? And what of every other movement that has happened since and will continue indefinitely? What could that possibly be? I am accustomed to understanding love as something that emerges through an individual heart, but that seems like a very small definition. What if every movement (yes, all of it) in existence is the movement and expression of love? What if the root of all of it, the foundation of existence itself is none other than love?
