What is BEING?

Can we define, calculate, capture the BEING? I think we cannot and if we attempt to do so we would end up considering the BEING as a thing. However the BEING is not a thing, it is not a sum of all things, we can only talk about it in metaphors. I would compare the BEING to a puzzle. It is a sum of all pieces put in a precise order so that it is equally important to consider both the pieces and the order they are put to get the full picture of the puzzle. As we are little pieces of the puzzle we can never grasp the wholeness and the meaning of it. We can have an idea of the whole but we can never fully comprehend it. We live in an era dominated by technology, we think that one day we will be able to control the flow of time and eventually become immortal. I think that it is just a crazy idea due to our incapacity to live in the uncertainty. Stating that we cannot grasp the whole implies an ethical assertion: we are limited and we must learn to cope with that.
