It is what it is, is the same thing as, I am that I am. The first statement is about something else, the second statement is about self.
Human understanding is not the first, last or primary understanding in the universe that causes all other logic in the natural world to function. Humans are not the standard. Human understanding is not the standard. Human understanding, no matter how certified by governments and their institutions or by masses of humans, is not the first or final word on I am, It is or Same ole.
Consider this example.
If a human doesn't understand what a snake is, and which one is poisonous, this does not change how the snake functions.
So now we go back to humans trying to limit the natural world to the limits of human understanding.
A miracle is simply something that has always been possible that humans didn't understand was possible. A miracle is an event that exceeds human understanding.Miracles are ubiquitous and commonplace because I am that I am and It is what it is.
Do not be deceived, some miracles are infrequent. Even so, they are still part of the Same ole, Same ole.
Same ole is khium uru or kha-me uru or Kh-amu uru meaning circle of waters in motion west is the same in the east, north and south.
Lastly, we can circle around once more and further clarify the word what and the word that as the same words. What is the question; That is the answer.
A companion pair is the question word Which and the answer word This.
