Take a look in the mirror. What reflects back to you is the radiance of your ‘rest mass’, your energy as a stationary object.
This energy that you are comprised of has no creation and no destruction. Your organism is alive with your energy as your body is in constant movement. Your energy is a burning fuel that heats and radiates from you.
All functions of thought, auto functions of lungs breathing, heart beating, actions of walking, running, eating all expend energy in forms of kinetic, gravitational, electric, magnetic, elastic, chemical, thermal and radiant. Energy is your beginning, but not your ending.
Essence is what you have become, what you are here, now, in this moment. Essence is intrinsic, indispensable, abstract and what makes each of our ‘characters’ unique. Essence in this forum is your past meeting y our present, requiring you to participate in your prospective future.
Your essence is what radiates from you and is observed and experienced by others. Your essence is fluid, it can be altered by your nurturing and nature, by truth and propaganda, by trauma or comfort, by your intention, actions and reactions. You are in the ultimate control of your essence, how you alter it whether effectively or negatively.
Since energy never dies, is always fluctuating essentially you are eternal. Eternity is a measure that has no ending. Eternal, as the continuance of your energy is perceived differently between cultures, within cultures and may be a question never answered during this life’s moments.
Some of the different beliefs are of eternal existence in a place of comfort and abundance or a place of pain and scarcity. Others believe your energy is reconnected in a different form returning to live a new existence as a new creature, or that you pass from this consciousness into Nirvana, a state of universal consciousness where you are absorbed into the whole and no longer an individual.
Whatever the journey is, it is of energy from beginning to no ending.
