Grounding is as much about a stable mind as it is about a stable body.
Grounding is a set of techniques to improve one’s connection to the floor beneath us.
In doing so the floor can be used as a support base. Learning to sink and relax to funnel incoming pressure to the floor aids balance and assists in maintaining position and angle. The ground can also be used to create compression to create power at short distance that when delivered correctly supersedes that of bone and muscle alone.
If you imagine your back against a wall and an individual pushing you from the front, you don’t go anywhere. Wing Chun teaches you to unite with the floor and use the ground as an equivalent support base meaning you can hold a position, lock a body in place, absorb incoming pressure, issue from the floor into an object, hold on to your balance and not fall down.
