站庄功的第四条口令 The 4th Instruction for the Standing Meditation

顶头悬
头要正，意念头顶上好象垂有一条线连于百会穴，把头悬起来；又好象头上顶有一物。这样，就可以使上身保持正直，头、颈也就稳了，同时还能防止倒地。

Hanging the head from Sky (Ding Tou Xuan)
Keep your head straight as if your bai hui were connected to heaven by a string, and visualize that you are holding an object (such as a bowl of water) on the top of your head. In this way your upper body will be kept straight and your head and neck will be very steady so that you will not easily fall onto the ground.
