Perennial means cyclic, not eternal.
Eternity is above the duration because it is the cause of duration.
In this having to move everything changes, and we are part of this all.
The blood is flowing because the stages of our heart rate alternate cyclically, as our breath, and yet... and yet, in all this to change, we continue to feel the same “ I “ around which we change skin, emotions, values, tears, but not this feel an " I "; that is a the same as all other beings.
This feeling of all that ” I “ said things that our intelligence can't ignore: it says that the same feeling ” I “ do not change as do our skin and our ideas.
Why not change?
Because the ego is the expression of our inner centrality, which does not change because it is not subjected to having to change.
Do not change because this centrality is absolute, and is the trace of the presence of the Mystery that is in us, as much as we are in it depending on the view from which you consider the existence, whether from the point of view of individuals and humans or Central view because divine.
Of course our ego is different for every being, but our knowledge of being that “ I “ it is identical.
Is identical because expression of the inner self that is the cause of “ I “.
Itself which is radiated from the absolute mystery, infinite and eternal.
Is this self that lives again, not the ego, and living it will feel to be an “ I “ again, but without the memory of all those ” I “ that are died.
Without that memory there may not be liability, and although again that ” I “ will have to pay for the mistakes made by the “ I “ that preceded it, that are in the memory of the central itself, cannot be blamed for those mistakes that are no longer in his responsibility.
The inner self, spiritual, of each being preserves the memory of all the states of the "I" in which it is expressed, but each new ” I “ is different from those who preceded him, although it has tasks to be accomplished that are inherited by all the "I" that recalled by the inner self.
That's why when asked Jesus who was the blame of the blindness of a man, Jesus answered that it was not his parents, nor of that man, but that his blindness had the task to show the greatness of God.
That greatness is also in piety that erases memories, and is the same that everyone gives you the possibility to be brave or cowardly, sincere or fake, man or devil.
Whoever despises others defects, giving them to hypothetical guilt that have had in previous existence, and consequently despise even those who bring the weight of those defects... chooses with that to be vile, false and demonic.
