Emptiness, what is it? And who cares?

The link above is to the website of teacher Rob Burbea. Specifically his teachings on emptiness.
This is the man who's responsible for teaching me most of what I know on the subject :) A man who himself expanded upon the teachings of buddhism to a brave new level. Birthing a innovative, grounded sense of freedom and personal agency into this world.
Sunyata is a Sanskrit term that is often translated as "emptiness", "voidness", or "boundlessness" and this is a concept and insight that is a cornerstone of each of the three primary schools of Buddhism.
This insight also leads to incredible, jaw dropping, degrees freedom when applied to experience.
This insight opens us up to our full potential as co-creators of our experience. Without the presence of limiting reified beliefs of solidity and certainty we are free to construct the world and sense of self that we are being called to create.
