Um was the closest being to the Primordial Void and the real essence of all. Um was devoid of the Pure Wisdom of True Wisdom, and thought itself different from the Primordial Void. Um thought itself as a individual being Independent from the Primordial Void. But it was able to enjoy Pure Bliss and Pure Joy.
As Um was able to understand Infinite Potential as a unending poll it was able to generate things.
It is because of Um that all beings can create things, multiply and live.
