William Blake said “The fool sees not the same tree the wise man sees.”
The wise man sees the myriad branched tree Yggdrasil, but not as other men see it. For he does not fall into identification with any particular branch of it. He sees this tree in the nervous system of the body he uses as a reference The term Centre is derived from a Latin root centrum, and from the Greek kentron, 'point, prickle, spike, an ox-goad. The 'ox-goad' idea is used in the sense of an 'incentive to action'. The root kenteo, 'prick, goad, wound' is cognate with cethr, 'nail'; and appears in the Old High..., as he sees it in the driving radiating forces of macro cosmos.
All the troubles of man’s world arise from inefficiency, from failure to respond adequately to the situation in which he finds himself. Failure to understand what makes things work, what motivates life; failure to understand what to do about failure to understand. “With all your getting, get understanding”, says the wise old man, looking back on his ill-informed youth.
