Yeah I actually got into esoteric martial arts quite heavily, spent literally 1000's and travelled to Malaysia from the UK twice pursuing 2 seperate esoteric martial arts.
I got burned badly, but it was a great journey to have experienced. Though because of that experience (and my experience as a muslim) i'm very weary of 'spiritual folk'.
One of the positive aspects of any martial arts is that it provides a practitioner with a sense of structure - which is essential to psychological health.
I initially got interested in esoteric martial arts because I was interested in finding an art that could teach me to kick ass, assist me in personal growth, and could lead me to 'enlightenment'.
After my experience I realized a few 'truths' regarding martial arts;
Matt Thornton (renowned martial arts instructor, and martial arts philosopher) came up with this concepts and perspective that I now agree with;
1)
Aliveness.
In order for an art to be functional for the sport of the street, it has to utilize unchoreographed and uncooperative what's called the I-method.
You introduce a technique or principle by practicing it without resistance.
You practice that technique or principle in an uncooperative and unchoreographed drill, mimicking the same resistance you'll encounter from an opponent.
You pressure test that technique or principle in sparring (various levels of resistance), or self defence scenario replication (various level of resistence)
Every combat sports gym follows the above methodology, even if they don't articulate it as aliveness or the I-method. The only other way to develop functional martial skill is by getting into regular fights - which isn't sensible.
2)
The warrior mentality vs the beggar mentality.
The beggar mentality is that you will 'bow' to those you deem of a higher status to you, and you expect others to 'bow' to you who you deem of a lower status.
The warrior mentality is that you don't 'bow' to anyone, and nor do you expect anyone to 'bow' to you.
IME esoteric martial arts can foster delusion when it comes to one's fighting ability because moves are practiced in choreography and cooperation. Skills aren't pressure tested in a contact drill, sparring, competition, or scenario replication.
It also fosters a beggar mentality, where deference to authority, and faith in authority is cultivated. If you question the effectiveness of the techniques you are encouraged to have faith in the teacher, or art - you aren't provided with evidence via pressure testing.
I think that arts based on aliveness, and the coach-athlete relationship are a healthier structure - spiritually and martially. And I realized that I have no idea what enlightenment is, and it's easy for people to present themselves as 'spiritual adepts' when they are surrounded by yes men, and keep statements and assertions vague.
If I had my time again I would have learned no-gi BJJ/submission wrestling for enjoyment and personal/spiritual development.
