Tai chi and kundalini

Top tai-chi practitioners have been said to be able to achieve the highest level of chi activation through the practice of tai-chi alone, without going through the Taoist meditative approach of Neidan. What is this highest level of chi activation? It is none other than the process of kundalini awakening, which explained in its physical essence is the activation of one's tailbone through one's breathing mechanism: no more, no less!

How can one activate one's tailbone through tai chi? It is through the training process of "Tilting (one's) tailbone" (收尾閭), with defined mindfulness specific for the training objective of activating one's tailbone. Like other advanced techniques in the internal art or chi-meditation, the theory is simple, but the successful training of which presupposes a strong foundation in the groundwork. Those who think that they can't do it because the secret has not been reviewed is, most of the time, wrong. Anyway, the following is my method that I like to share with you, my reader:

1. Do zhan zhuan. 
2. Mindfully "sit" (坐), which presupposes a good opening of one's pelvic joints (kua 胯) (which opening needs different training routines). Assuming that you have an opened Kua, you need to mindfully feel it as if (i.e. visualization) you are doing weightlifting (see photo below), but with your torso (almost) upright and knees only bent slightly. 
3. Do abdominal breathing (check my posts on the subject) 
4. When you're onto the breathing rhythm, synchronize the breath-in with the tilting, i.e. breath-in, tilt (with relaxed power), breath-out, relaxed (no power).  With practice (probably more than one session!), your tailbone will be activated, and you can feel it.
5. Result: energy will be stored in the tailbone (i.e. if you can feel the stored energy, you had it!) ready to move up the spinal cord or the central chi-channel, or for other purposes.
