True Fajin is like a whip

When watching the mechanism of Master Hwa's punch unfold and deliver power one sees a representation of how a whip unfolds and delivers power. When striking an opponent using Fajin Newton's 3rd law of action and reaction is in effect but a reaction cannot come back... because, like the whips "softness" after the strike, so is your Fajin arm/body The rebounding force dissipates at the opponent's body and does not come back because of limpness in the arm after the strike.
