I seek harmony between doctrines of Idealism and Realism to account for human existence. I welcome thoughts from all directions to understand the nature of Human Identity and Individuality. The multicellular human organism exists as Physical, Mental, Social, Moral, Spiritual being with a Creative Form that cannot be duplicated. For purposes of brevity and simplicity, I divide the human being into two categories; 1.The first is 'SELF' and it represents man as Physical, Mental, and Social Being and 2. The second is, the 'KNOWING-SELF' which represents man as Moral and Spiritual Being."I am Consciousness, therefore I am", is the proposition that I use to understand the nature of man's Identity and Individuality. Man is a Mortal Being whose Life and Death are operated by Oxidation-Reduction Chemical Reactions. The Physical Being is dissolved by the powerful influence of Time which seem to operate Natural Law of Aging. Things in Nature change with Time but the Identity and Individuality of Man remains the same during his Life Journey. The genotype remains unchanged while the phenotype appears to be changing all the time. In the multicellular human organism, the Consciousness functions to establish Identity of the organism and to defend its Individuality. Consciousness also establishes the Connection, Partnership, Relationship, Yoking, Joining, and Association between the energy dependent man and his energy provider. Man exists in Nature because of his ability to acquire energy from external environmental source. Consciousness in its essence refers to this awareness of energy dependence. I describe the Connection between energy seeker and energy provider as 'God Connection'. Man during all the stages of his existence, and under any given circumstance, either in good health, or ill-health exists on the basis of this 'God Connection' which is an attribute of biological or living function called Consciousness. This conditioned nature of human existence is supported by Power/Energy/Force which can be experienced as Compassion/Mercy/Grace of the Creator who created man as an Individual with unique genome that has never existed in the past and also will never exist in the future. I seek the Unity of Man in Body, Mind, and Soul unlike other common Indian traditions that seek to verify Identity between Human Soul and Divine Soul. My doctrine can be described as Unity Theory of Non-Dualism.
