Consideration of any “thing” entails full exploration of its meaning, including all contexts and antonyms.
Fear is a context that shades meaning of each “thing”.
The unknown arises because fear prevents its consideration.
Therefore fear, unlike joy, disgust or sadness, has to be subsumed in order that the unknown “thing” can be considered. That is, it must be seen as context, separately from the “thing”.
This perspective is achieved by accepting the worst feared outcome, by plumbing the depth of possibility.
Death is an antonym of, and also a context of life. The opposite is also true.
Fear of death is a surface reflecting our ego. It is a narcissistic mirror at the boundary of the ocean of existence. It’s reflective property is a barrier to our consideration of existence.
Fear of death prevents the conscious consideration of a deeper monster – existential angst – whereby we fear utter meaningless of infinite non-existence.
When existential angst is plumbed it is found to be a chimera, a confection of our ego; however it must be confronted and experienced for this this truth to be released.
It is by swimming naked in the infinite sea of potential meaningless that meaning emerges.
It is through integration with nothing that number and all “things” are realised.
It is through this mechanism that death is dissolved through a wider perspective, so that the joy of unification with “all that is” is glimpsed as the truth. “All that is” is synomymous with “the word existing beyond time”.
Some do not have to travel this path to truth. They are most often securely attached and live confidently (with trust). This is most often a gift from their parent, who held them in maternal reverie through their perilous crossing to the world of “things”. They are blessed.
