Re: Aikido™ and Aiki…do. Where are we at?
I would stand under a waterfall if:
a) it were a hot day and the water was nice and cool and refreshing
b) it was a normal day, and the water was nice and warm and soothing to my neck and back muscles
c) if I were trying to work on my mental intention(s) and I wanted to focus all of my mental intention of every part of my body say rising up - and I thought it might help my concentration to have the water pooring down on me while I worked at it.
d) if had some ability to focus some internal heat and I wanted a "challenge" by doing this on a cool day under cold water.
Those are the only reasons I could come up with.
