What is it about our individual existence that keeps us from knowing we are who we are? A constant self reminder that when we wake up in the morning from a good (bad) night sleep we are still the same person the day before, even though we are a day older, losing a few brain cells or losing a few strands of hairs or losing (gaining) a few kilograms. It gives us a sense of our individual identity.

The answer is obvious. Still it could appear surprising to some people. That it is the individual proximity of the mind in the brain. The mind could never truly connect to the brain. Similarly, water and oil could never become one inseparable substance but only in colloidal states. The fact is brain is made of matter (quarks and leptons) while the mind is of energy or at its most complete states square of energy. In the final analysis, all matter and energy are just squares of energy (quanta of space-time).

However, when the mind is a little bit farther apart from the brain, the physical body ceases its active vigorous functions and goes into deep idleness. When the mind–brain separation reaches a threshold distance or a point of no return, disconnect is permanently the eternal slumber of physical death or matter death. Nevertheless, the decomposition of matter (e.g. proton decay) is just a prelude for the liberation of the mind from the brain that is the search for freedom (becoming one independent being) is a universal preoccupation. This search becomes all the conservation laws and invariance principles of nature in the physical sciences as well as in the life sciences involving both objectivism and subjectivism.
