Greetings Jean Noel,
I have been worrying about you and your joints
So I'm back with more suggestions, hope I can help a little.
Firstly, may I suggest you consider if it is indeed Taijiquan you should be seeking.(sometimes seeking the wrong thing can be frustrating and futile). Ask yourself...Why Taijiquan? Why Taijiquan as opposed to another martial art or meditational art? What has lead you to discover Taijiquan? Has it been a recurring theme in your life? Any funny coincidences? You mentioned that you ordred some literature on the subject...Have any books ever 'fallen' into your possession, through friends, or used books which just caught your eye, etc...Do you find patterns? Are there signs from your overall life which point you in this direction?
Studying your present life and your past experiences can help to guide you in your future endeavors.
If it is truly your 'path to follow', then I must warn you that there are also the factors of 'time and place' which must then be taken into account.
Sometimes, we are simply feeling a 'preview' of what we will be doing in the future, but it is the wrong time. Sometimes this is difficult to accept.
For example... All my youth, I believed that I would somehow be a racehorse jockey(amongst other things)even though,i lived all my youth in the city, with no such possibility, I hadn't even been in contact with a horse.I had a strong feeling that maybe I sould pursue this field.due to lack of opportunity, I put it out of my mind as a fanciful thought.Many many years later, despite the chasm of geography and lifestyle, I was recently given the opportunity to become involved with sulky race horses. I grasped this opportunity,became an apprentice in a small stable, I cleaned out stalls, groomed the horses, learned all I could, and then was given opportunity to actually train them for the races. When given the option of racing, however, this did not work out quite as I had thought many years earlier. I discovered that many of the jockeys were so aggressive about winning that they would do anything, including pushing a fellow jockey into a heap mangled up with his horse onto the side of the track. So, actually my feelings I had many years prior were along the same lines, the feeling was right. the timing was off.
Our feelings and history must be studied, and we must adjust our goals accordingly as we go along. Be open to possibility and set nothing in stone. Maybe it's now, maybe it's later, maybe it is something slightly different...Investigation of these aspects might help. Feelings are usually significant of something.
Other times, we are seeking the right thing at the right time, but are in the wrong place...This would be crucial to your success of course. Only you can judge as to the importance of what you seek. Only you can take the appropriate steps toward your goals, and make the necessary changes required.
Usually things we 'should' be doing just happen without effort, but there are times when we must make small efforts to overcome minor obstacles. If you work and work and work and get nowhere, may I suggest it is perhaps the wrong time,place, or thing you seek.
To overcome the small stuff requires a certain amount of trust and belief in what you are doing. We must first discard the old to create a space for the new. We must abandon to regain. We must close a door first in order for another to open. Then the opportunity for new growth should occur, the opportunity should present itself.
Create the opportunity through positive, focused thinking, and taking the concrete steps to to assist in propelling these thoughts.
Disscussing your dilemma here was a concrete step, even if it hasn't produced a master for you, yet. Place ads requesting a teacher, but you must try to believe that results are possible. I've seen others place 'seeking master in such and such an area' placed here on the boards. Daydream about being a master, if you paint, express your wishes on canvas with brush etc...the important thing is to manifest your needs in a real manner, focus and attention are the essential factors, chant to yourself something motivational and positive every night before sleep .....Pay utmost attention to your thoughts to provoke a positive reaction, then, just 'let it go'. The momentum you have set in motion with concrete action must be given time to process, obsessing about it would interfere. Let go, not necessarily by forgetting about it completely, or even necessarily for a long time, but do try to change your mind to a different subject for awhile. Keep your eyes opened for signs and coincidence. Investigate these to see where they lead, and when the opportunity does arise, grasp it with both hands and all your determination and change whatever will have to be changed.Don't give up over minor obstacles. Perseverence is Paramount.
Probably enough hot air here to fill a blimp!
