I think some years back, Harry sensei shared with us a physicality of extension.
He says as we walk, we should extend out our fingers, be conscious about your palms when you walk. More often than not, the fingers are slightly curled inwards, at best. Perhaps, balled up in a fist, at ‘worst’?
So I began that habit, so when I walk, my palms are straightened, as much and as often as I can remember. My palms are slightly open, extended. not overly extended.
It was a small habit, and I can tell right now after years of doing that, the fingers are much more relaxed and when I move, I can mentally imagine the direction of move from the tip of my fingers.
It is likened a paint brush, my fingers, you cannot paint a good, decent painting when the pain brush bristles are curled. Bristles are straight, soaking up the colours and putting them on the canvas.
Our fingers are like paint brush, and they cannot paint a beautiful picture if they are curled. Only when we open our hands, exposes out heart, exposes our vulnerability then there is a chance for our lives to improve.
