aijiquan for martial purposes, you should perform the sequence continuously three times, both morning and evening if possible. The first time is for warming up, the second is for qi transportation training, and the third time is for relaxed recovery.
How to Practice Taijiquan Sequence
Normally, it takes at least three years to learn the taijiquan sequence and to circulate qi smoothly in coordination with the breathing and postures. You should then learn to transport qi and develop qi balance. Even after you have accomplished this, there is still more to learn before you can be considered a proficient taijiquan martial artist. You must learn how to strengthen your qi through practice, you must develop a sense of having an enemy in front of you during the sequence, and lastly, you must learn how to train jin during the sequence.
In taijiquan, qi plays a major role in jin. When qi is strong and full, then the jin will also be strong. An important way to strengthen and extend your qi is to practice the sequence slower and slower. This is the yin aspect of taijiquan practice, which helps you to build both a strong, concentrated mind and internal qi. If it usually takes 20 minutes to finish the entire sequence, increase the time to 25 minutes, then 30 minutes, and so on. Do not add any more breaths. Everything is the same except that every breath that is used to lead the qi gets longer and longer. In order to do this you must be very calm and relaxed, and your qi must be full like a drum or balloon, first in your abdomen and later in your whole body. If you can extend a sequence that normally takes 20 minutes to one hour, your qi will be very full and fluid, your mind calm, and the postures very relaxed. When you do the sequence at this speed, your pulse and heartbeat will slow down, and you will be in a deep self-hypnotic meditative state. You will hardly notice your physical body, but instead you will feel like a ball of energy. When this happens, you feel you are transparent.
Develop a Sense of Enemy
Even when you can do the form very well, it may still be dead. To make it come alive you must develop a sense of enemy. When practicing the solo sequence, you must imagine there is an enemy in front of you, and you must clearly feel his movements and his interaction with you. Your ability to visualize realistically will be greatly aided if you practice the techniques with a partner. There are times when you will not use visualizations, but every time you do the sequence your movement must be flavored with this knowledge of how you interact with an opponent. The more you practice with this imaginary enemy before you, the more realistic and useful your practice will be. If you practice with a very vivid sense of enemy, you will learn to apply your qi and jin naturally, and your whole spirit will melt into the sequence. This is not unlike performing music. If one musician just plays the music and the other plays it with his whole heart and mind, the two performances are as different as night and day. In one case the music is dead, while in the other it is alive and touches us.
If you don't know how to incorporate jin into the forms, then even if you do the sequence for many years it will still be dead. In order for the sequence to be meaningful, jin and technique must be combined. An important way to do this is to practice fast taijiquan. Practicing fast taijiquan is part of the Yang aspect of taijiquan, and it allows you to manifest your internal qi into external forms and power. Once you can do the sequence of movements automatically and can coordinate your breathing and qi circulation with the movements, you should practice doing the form faster and faster. Remember, if you ever get into a fight, things are likely to move pretty fast, so you have to be able to respond fast in order to defend yourself effectively. If you only practice slowly, then when you need to move fast your qi will be broken, your postures unstable, and your yi scattered. If any of this happens, you will not be able to use your jin to fight. Therefore, once
