A verse from the Gospel of Thomas as translated by Thomas O’ Lambdin.
(18) The disciples said to Jesus, “Tell us how our end will be.”
Jesus said, “Have you discovered, then, the beginning, that you look for the end? For where the beginning is, there will the end be. Blessed is he who will take his place in the beginning; he will know the end and will not experience death.”
If you begin a long mathematical computation and your first calculation is incorrect, what can be said of the remaining calculations?
Can the computation be corrected as it moves on down the page?
Can it be corrected by going back several levels and recalculating?
How do you truly correct a long, multi level computation?
You go back to the first calculation and correct it!
The only way to correct the ending is to correct the beginning.
