From the moment of birth - you (the body), exist in a constant default state of deprivation and lack. This body is a 5-sensory composite of needs, wants and desires, which are not easily satisfied. Indeed, you can never be fully satisfied, for this is the nature of the mechanism we find ourselves in - ever craving, never filled.
You spend all your conscious, waking hours attempting to fulfill these deficiencies and needs - mostly unsuccessfully. These needs and wants come in many forms; from craving various sensory pleasures to satiating biological needs such as hunger etc.
Everything motivating and driving you, is due to you existing in a state of lack. Whether it be physical or psychological.
For example - You are sick, so you seek relief. You are lonely, you search for company. You are bored, you crave mental stimuli/distractions. You feel inadequate, you yearn for recognition. You feel depressed, you seek serotonin and dopmaine hits.
All action then, must stem from a deficiency - be it subtle or pronounced, for surely something that was "whole" would need for nothing?
So, that is all life is. A chasing after sustenance.
There is nothing to be gained from the whole affair - no profit whatsoever. It is a get-out-of debt system. A race to the start line.
All "positives" are simply just the elimination of negatives and a successful satisfying of biological deprivations. All we are doing is striving to remove burdens and attempting to fulfill bodily needs/cravings which have been imposed upon us by our own biology. To make matters worse, the state of lack never goes away until the body dies, yet the means of fulfilling ones needs decrease as we weaken with age.
We are essentially existing within a "deprivation chamber" and all we are doing, is struggling to get gasps of air. Fools will say they have "gained something", but the wise know better. The best one can hope for, is perhaps an excessive satisfying of deprivations and relief. But if that be the case, what merit was there in coming into existence?
There was none. Better never to have been.
