Need/suffering, is the experience the sensation - of temporality, of (inter)activity, in other words of existence.
Modernity shelters...did I not say this?
Pain is an extreme form of suffering.
It is need not satiated for a period of time, to where it begins indicating attrition upon the emergent unity - the self-organizing organism.
Need is the sensation of lack.
What is lacking?
The absolute...the perfect, the complete, the Idea(l), the Here, the Now, The Self, the Thing, the One, the God, the Being....use whatever metaphorical, symbolism you like.
What is this "absolute"?
The question presupposes its existence.
It is because the absolute is absent that it can be imagined in any manner the mind needs to cope.
how does the mind construct its model of the projected absolute?
It gather data from the past, and combines them into new forms, projecting them, using the imagination, as a 'towards' as an object/objective, that directs the Will.
Will directs the aggregate energies/processes, of the emergent self-organization we call an organism.
The more detached form reality this projection is all the more fantastic, unreal, supernatural, unnatural it is.
Nature is the past, the sum of all nurturing.
To Know Thyself, is to be aware of your identity, to know your past, which you are a manifestation of.
Need/Suffering/Pain is this self-organization resisting, temporality...the Flow towards chaos, the disordering.
