Loosely translated, Fajin means “to issue power”. There are lots of explanations for this phenomena, from relatively simple to rather mystical.
Practically speaking, Fajin is a way of generating power, more specifically short power for striking or grappling applications in the martial aspects of Taijiquan. Training Fajin can allow you to generate tremendous amounts of power over short distances, something first popularised by Bruce Lee’s one inch punch. If you’ve been studying Fajin for martial purposes for any length of time, you’ll probably have realised that that sort of power is your bread and butter power for martial Taijiquan.
This doesn’t mean to say that Fajin does not have its applications in the healing discipline within Taijiquan or any internal martial art. “Soft” Fajin is a way of practising Fajin that allows the body to experience gentle impact to stimulate the bones and allows the body’s Qi to circulate more freely. Practising Fajin is also a useful way for the Taijiquan practitioner to “self-diagnose” areas of tension or Qi blockage within his or her own body, as the wave of power will travel and stop at any points of tension or blockage. The practitioner can then practise to relax these areas in his normal Taijiquan form practise. Fajin for health is not often taught these days, and it is a point of interesting historical speculation as to why it was not emphasised in the modern teachings of Taijiquan.
Biomechanically, a Fajin is nothing more than a vigorous shake of the hips, allowing the wave of power to move up through the body and then out through the hands, much like the force travels through the hanging ball bearings on a Newton’s cradle. Whilst this principle is very easy to describe, the practise of it is slightly more tricky because the body has to be relaxed enough to allow the power to flow.
Much of the initial practise of Taijiquan is aimed at relaxing the body, because this relaxation is required for effective Fajin to take place. Once the body has achieved a baseline of relaxation, then meaningful Fajin practise can begin, and each posture of the Taijiquan form can be used as a short Fajin drill.
If Taijiquan is all about balance, the soft, slow movement of the form has to be balanced by quicker, harder movement, which we believe is the role that the practise of Fajin in the cultivation of health fulfils. In the next post, we’ll talk a bit more about why Fajin is so good for you.
