In Tai Chi we talk of "the silken thread". We imagine that an invisible thread that connects the crown of our head to heaven. At the other end - on the soles of our feet there is a spot called "the bubbling spring". If you wish or if your condition dictates you may do these exercise sat; but if you do you should ensure that you put the soles of your feet flat on the floor and you must still visualise the silken thread and the bubbling spring - and all of the things learnt in the previous sessions - i.e. ... Circle Breathing, The Three Gates etc.

Relax your shoulders and then, focus you attention upon the position and placement of your head. In Tai Chi we call this "exquisite self examination". Find the place (there is one!) where your neck and shoulders can be relaxed and your head may 'rest' there without effort. This (eyes looking directly ahead/chin up a fraction) is the only 'effort' this this first 'preparation' part of exercise that is required.

Think about this: The most frequently used visualisation in Tai Chi is that of a ball … or more precisely, balls and circles of various sizes; from that of a beach-ball, held between our in-turned hands when doing "Embracing the Tree", or, as in this instance, i.e. simply standing in preparation, as a sphere about the size of a tennis ball that we hold against our neck with the underside of our chin.
