To be born, living, and then, dying, is no trifling.
Beasts are born, do whatever with each other, hence procreate, and then die. Ever a beast.
Were we humans to do the same, and no more, we too would be non-different from the common-lot animals. Is this all that we are - another species of simple animals? Who are we? Are we just some two-footed beasts, and nothing more? What are we? Where do we come from, where do we go? Are we just the body, or something more?
An intelligent person perforce, at some point of time in life, asks such questions of himself or herself. If one does not, one must. Otherwise one may well be dead already, come and gone. Without a coo, ever a cuckoo. An unsung life, its melody lost, sans a thong.
So, why the hell are we here?
We are here for Self-Realization.
That is, we are here to live a joyful life - by getting the Nature of Reality. To understand ourselves. Better still, we are here to "get" the Self - the inner "make" of our life, and the true nature of the universe we live in. In a nutshell, we are not here to be insane with ourselves, or be stupid with others; but to discover our true self - the Universal Self.
Now, the question arises, "How the hell do we get to know whatever all this is?"
Obviously, our normal everyday understanding of things just makes us simple fellows, if not simpletons. That is to say we normally get it only so far that we are "something" alive. And are seemingly but some sort of bumbling biological entities. Soon chemicals! We die.
Where do we go then, after death? In fact, how the hell do we get here?
Are we just a silly folly, here because of a little hanky-panky done by our parents?
Metaphysically, it is held by freemystics of a higher "knowing" everywhere, that until and unless we "get" the Self - our inner reality - we are born again and again, ad infinitum. As a lower, or a higher species, as per our karma. As a direct consequence of our good or bad deeds.
Thus, we either evolve, or we devolve.
And thereof, either we get a basic understanding of who we are, or we do not. If we do, we live and die not entirely a dumb idiot, but with at least with an inkling of and about where we are going hereafter - in the after life, and after death. Or we are lost. Live, and die similarly. In the embrace of Which Is, or lost forever unto what is not.
Simply stated that would imply that we either die knowingly, and peacefully unto the realm of the Ultimate Truth; or we live and die unknowingly, a simplistic superstitious myth.
