As soon as I have a finished mental conception, a full idea even of myself, then dynamically I am dead.

To know is to die.
But knowledge and death are part of our natural development.

Only, of course, most things can never be known by us in full.

Which means we do never absolutely die, even to our parents.

So that Jesus' question to His mother, "Woman, what have I to do with thee!"-- while expressing a major truth, still has an exaggerated sound, which comes from its denial of the minor truth.
This progression from dynamic relationship towards a finished individuality and a finished mental concept is carried on from the four great primary centers through the correspondence medium of all the senses and sensibilities.
