It seems simple to me that we are hear to learn and when you don't listen to your "head" the universe will "trip" you up someway with any physical interaction to change your attitude or direction in life.Anything from an ant bite to a car accident to a stubbed toe or headache. So if you don't like physical pain listen to your little voice that saves your ass. A good exercise is to cut a deck of cards and try to "guess" what the suit, number than individual card. I have taught two 7 and 9 yr old aboriginal boys this and they read my mind as I would "transmit" the card to them. They would get a dozen in a row. Tune your mind like a radio!!!It is easy. "First you must trust yourself then you can trust others"
Anyway your legs are your under"stand"ing and your arms are your "act"ion. As humans we ACT and we UNDERSTAND.
We stimlate our hands much more than our feet since modern times off padded shoes, concrete walkpaths, padded grass.
Look at a native that walks on rough ground stimulating his feet, he is in balance with himself and the planet.
This is what got me into "reflexology". It is amasing the pain people hold in there feet. The neglect of the furtherest thing from our head in a metaphysical sense creates an imbalance in what we create(action, technology) to the wisdom(understanding, ethics) that is put into that creation therefore we (as a majority) are out of balance. So go and get a good foot bashing and rebalance your life.
Hope that was not to deep
