I can describe my essence (What I am) if and only if it is preceded by my existence (What I do). While existing in the earthly realm, my claims about my true essence, that which makes what I am, true substance underlying my physical manifestation, most important quality of my human form, may exist only in the language it is expressed, or in the mind in which it is conceived. My claims about my essence will be valid if it has correspondence with an external reality.
In my view, the ‘Essence’ and ‘Identity’ of a thing can be described if, and only if the thing had a past ‘Existence’, or is existing in the present, or has the potential ability to exist in the future. Essence and Identity are predetermined by the requirement called ‘Existence’.
Existence’ becomes the defining feature or chief attribute of all things. And, without the fact or reality called ‘Existence’, no truth can be known, and things have no Identity or Essence.
The word ‘Essence’ (Latin. Essentia) describes that something which makes an entity what it is; intrinsic, fundamental nature, the most important quality of something to constitute its essential being. Essence is used to describe the inward nature of anything that is important to know its manifestations that can be physically observed. The word ‘Spirit’ or ‘Soul’ are often used to describe the ‘true’ or unchanging principle of man for man’s physical identity is not constant.
The term ‘Identity’ (Latin. idem) means the same (Sanskrit. idam). The Latin word identitas is related to Latin. essentitas and hence Identity and Essence are always related and they help to know the thing or entity that they describe. Identity is about the condition or fact of being the same, or exactly alike, sameness or oneness.
In modern times, identity is about the condition or fact of being a specific person or thing. Whereas the term ‘Individuality’ describes the sum of characteristics or qualities that set one person or thing apart from others. Individuality is the condition of the Individual who exists as a single, separate, or particular thing. For man, his Individuality sets him apart from all other men. The term ‘Existence’ (Latin. existere, or exsistere) is about the act of existing, the state, or the fact, or the reality of actual being. Existence demands that the thing or entity must come forth, stand forth, to manifest, living, or being alive. The term ‘Unity’ implies the state of being united to make something complete in itself, the quality or fact of being a totality or ‘Whole’. Unity is used to signify a Complex, the product of a Union of related parts, or an arrangement of parts that will produce a single, harmonious effect. Unity is thus concerned about the ‘Effect’ it generates while a thing could be made up of diverse elements or individuals. For human body is constituted by trillions of Individual, and Independent Living Units called Cells, the ‘Effect’ called ‘Unity’ is of fundamental importance to know man’s ‘Essence’, or ‘Identity’ that is manifested by his ‘Existence.
Existence (What you do) always precedes Essence (What you are). What God did for Six Days is the fundamental basis for knowing God’s Essence.
