Were I to put aside rationale, what would remain?
The irrational.
What, then, would fuel logic?
The illogical?
If I were to put aside matters of the physical self, what would remain?
The spiritual?
Let us say I am nay a spiritualist, for the spirit is associated with that which is supernatural, which in this mind exists not.
Mentality must be naught, as mentality would grasp to the forementioned physicality or rationale.
What then must be left, aside from the goal? The work.
Work is defined as any exertion of energy.
Let us expound then, on this: what is the great work?
Energy must be exerted to continue a lifecycle. Consumption, excretion, and rest are work.
Work, then, may be described, as that which one must do to survive.
What is greater than this?
If you were asked to choose between a path that would surely bring you great happiness, and one that would bring great joy, which would you choose?
Work is the path that leads to happiness. Happiness can be described as an ecstatic feeling, however, one based on circumstance and consequence.
The great work, then, must be the path to joy. What is joy? A deepseated ecstacy, that really can not be described as a feeling at all, rather, the sum of many emotions, from which, others spring. This is not based on circumstance or consequence, so much as it is derived from being. Can that which is not based on circumstance and/or consequence be finite? Can something, such as joy, that has no origin, and that never actually "came to be" cease to exist, or will it endure?
So, backing up then, we have said work is that which one must do to survive.
That said and knowing as we know, the great work is that which one must do to endure.
More specifically, then, what must one do to endure?
Simple. Separate that which is derived from circumstance and consequence, from that which is derived from being, and kill it.
