Another piece of wisdom from the Zen Master, Bernie Glassman in The Dude and the Zen Master :-
And its constantly changing. That’s why it makes no sense to be attached to outcomes. Only how do you not get attached to outcomes?
This is good advice that can be applied to doing push hands. Just go with the flow. Don’t try to impose or force an outcome. Or as Jeff Bridges said in reply to the above :-
Just throw that fucking ball. Just do it. Get into the thing, see where it takes you.
Simple advice, isn’t it. Yet, how many times we insist on using more strength, even throwing up tons of excuses as to why we must learn to use more strength so that we can win the shoving match instead of just letting ourselves go with whatever the outcome is, actively feeling the opportunities and when a suitable one comes along slide into it, trap the training partner’s movements, control his space, his ability to respond and his balance, and before you know it he has given up with you barely using much to do it.
In short, help your training partner to help you checkmate him.
