In Gregg's model, it would seem to be implied that all human behavior is rooted in the emergent level of mind, or animal behavior, that emerged with nervous systems, which would suggest every level (of life and physics) below as exponentially inert or irrelevant.
Yet, I'm increasingly suspicious that our behavior, inside and out, is rooted in the very ground of being (energy) somehow more expressed through our nervous system, which is especially integrated yet complex enough to express the cosmic "self".
In other words, any search for the root of human behavour or self will never end.

PS: some extra quotes if interested:
"Their is no protection to be found in the seeking of fault, neither within, nor without. To seek fault is to ask for it."
"Fear that others might think you are guilty when you know you aren't seems to attract a guilty verdict even though you're not guilty".
"Identification with fault or loss is the same thing as the Christian concept of sin (missing your mark) and the true cause of physical illness and death...no kidding."
Fear is identification with loss
Worry is identification with loss
Humor is realized liberation from loss, and often at the expense of those who still identify with some loss (superiority + relief theories of humor)
Forgiveness of debtors is dis-identification with the loss of not, or not potentially, getting paid back.
The buddha self can't be named just as God Is nameless, which is why no karma attaches to God - the true self of origin.
Whatever we identify with in our minds, karma attaches to, based on simple logic.
"whoever identifies with loss, loss enjoys to ruin"
"Behavior according to external morality is service to fear more than love, thus distrust of one's own self. True morality is merely the way of one's own heart, and trusting one's own self to be faultless, blameless and perfect, knowing no good-enough reason to assert otherwise. "
