The Work is a shorthand phrase that refers to the essential work of Healing and Connection (really Reconnection) that is necessitated as a consequence of a Toxic Socialization process that damages the Physical Unit and disconnects us from Highest Self. Put another way, the Work is the psychological, intellectual, and emotional process of merging the Bodily Ego with the Spiritual Ego.
Compare The Work to The Great Work.
It is important to note that, the Work is not an operation that we conduct on our souls. That is, the Work is not an alchemical work of soul purification. Your "soul," your Highest Self, is already perfect and requires no moral, evolutionary, or spiritual development whatsoever. It is your physical unit that is the problem. Thus, the Work is the work of healing the Physical Unit so it can reConnect to its own Highest Self.
