Since Einstein we have known, with scientific certainty, that energy can neither be created nor destroyed, and that everything in the universe consists of energy. I feel and think that energy is the spiritual as well as the physical substance of the universe, a singularity capable of transcendence. This singularity has transcended its state and transformed its forms many times while remaining the energetic singularity of the source. (Energy can't be pluralized; there is only one energy!)
"Transcendence" means that energy transcended itself while remaining what it was. With every transcendental step, energy carried its previous state or form forward into the next stage: development trough envelopment: transcend and include, transcend and include, transcend and include, etc., ad infinitum. Thus, we still are the eternal energetic singularity of our source. In fact, this is what we ultimately and eternally are. The eternal energetic singularity is our ultimate source and our ultimate self. All of its transcendental stages, states, and forms are more or less temporary.
Thus, when we look at the death of the individual human organism from the viewpoint of the eternal singularity, then this death is just one of the countless changes that eternal energy undergoes while remaining an eternal singularity. When the life of a human individual is contemplated from the detached viewpoint of eternal energy, then it is a mere temporary and very brief flicker.
We often are in awe of our source. But, if the source were capable of awe, then it would be in awe of us, its most accomplished creation. When the source evolved us, it became capable of awe, and thus is in awe of us, its most perfect creation--so far. But the source is not saddened by the death of one of its most accomplished, biological forms. From the viewpoint of our ultimate self, life and death are one.
The lamps are different,
But the light is the same:
One matter, one energy, one light, one light mind,
Endlessly emanating all things.
-Rumi
Out, out, brief candle!
Life is but a shadow, a poor player, who who struts and frets his hour upon the stage, and then is heard no more. It is a tale, told by an idiot, full of sound and fury, signifying nothing.
-HAMLET, Shakespeare
But life can also be an epic, told by an inspired poet, signifying everything: the immortal spirit. It is up to us!
If we are eternal energy, if eternal energy really is ultimate self, then we ought to be able to experience ourselves as such. We are! From my mystical viewpoint, experiencing ourselves as the eternal energy that we ultimately are is mystical experience. This is what we should strive for! And, once we have experienced IT, death will lose its sting.
