SAT and ASAT

The PERMANENT(SAT) & IMPERMANENT(ASAT):
The perspective of the JEEVA;
Though in life there is death of a moment with birth of another moment at all times, yet there is a sense of continuity like that in a movie where the individual pictures are telescoped so rapidly as to give a feeling of uniform continuity.
Looking back in life every moment is death of the past and birth of a future moment as the present.There has been death of the infant and birth of the child, the death of the child and birth of the youth,death of youth and birth of adult,death of the adult and birth of the aged.Then there is death of the body and most mind of this body and birth, after search of another woumb depending on the residual seed of ignorance in form of sanchita karmas(punarapi jananam punarapi maranam,punarapi janani jathare sayanam).This is a state of continuous change.The photos in the album of a Jeeva as a child,youth,adult,aged and the.....are absolutely different from one another in all gross aspects, yet one says that all this as me, without the feeling of change.There is thus something which is permanent and without a change in every body mind which witnesses these changes without being affected by these changes.This is the Atmana so named in the shrutis.
BRAHMAN is "satyam gyanam anantam ";eg. Existence,Consciousness,Bliss,Infinite.
The Scientific perspective:
From birth to death is a process of continuous change.
Change is there in Space and Time.In general relativity there is no separate space and time, rather there is a space time continnum.The changes( birth-death)is there only in space time.Any thing that changes has according to the laws of entropy and enthalpy; is bound to go from organised to disorganised; in other words from birth to death.
That which is changeless thus has to be beyond space and time since everything in space time is changable.
It is also known the entiety beyond space and time is infinity.
Thus except infinity every thing is changing( from birth to death).
Summary:
In me there is an unchanging element which witnesses over the changing gross elements of body mind.Since that unchanging is infinity; and in me there is something unchanging; thus it has to be INFINITY and nothing else.
Mathematically infinity can never be two as one will limit the other infinity and make it finite.
Since BRAHMAN is infinite as per shruti(aitt.up.).
In me the I(atman), the unchangable is infinite witness.Since there can not exist two infinities.The I(atman) and Brahman are bound to be the same infinite.
Thus "aham brahmasmi"
