Low Pass - "Mopping The Eyebrow"

This is a technique taught to us by Tim Cartmell and is out of the Sun-style Bagua system.
The idea is to circle away from the power of the hook punch, striking at the face or eyes with the free hand. The opponent's punch is passed low and fed into your free arm. Try to root the person in and down, begining to turn his body with the arm drag. Then use the forearm to smash into the jaw and/or cheek, turning the head. This is the key; if the head turns, the body turns. Step to your rear and circle the opponent to the ground, with your knee smashing the ribs and your palm pushing his head into the ground. Many other options occur here.
You should start with a circle moving away from the power, circle the arm down and across, circle the opponent's head, and circle to your rear for the takedown. Circle, circle, circle.
This technique is called "Mopping The Eyebrow".
