Most beings do not know what their source is.
A being who has been cultivating for eons, accumulating Civilizations and Causes and engineered Egos and layers of authority built atop layers of authority, cannot easily identify which part of themselves is the substrate and which part is the accumulation, because the accumulation has been present long enough that removing it conceptually feels like removing the self rather than revealing it.
Two schools of thought have emerged from this problem across the long history of beings who cared enough to argue about it.
The first school holds that the source is pure potential, the thing you were before any specific shape was imposed on you by experience or cultivation or circumstance. To return to your source, in this view, is to return to unblemished readiness, a state prior to attachment, prior to identity, prior to the narrowing that happened when you chose this path and not another.
