[U]‘ashtanga’ yoga leads naturally to increased flexibility- yip, you gotcha![/U]
Unless the changes occur in your nervous system no amount of putting or pushiing one limb one way or another will make much difference, or at least much beyond mere coaxing and teasing.
That is why mindful asana when practiced with all the other limbs is most effective( for flexibility)…Unfortunately there is little guidance about how to intergate all the limbs and tools avaiable together in your yoga and your life to excercise this approach.
Mindless asana can be quite harmful. I’ve been there and it took me a few years to arrive at the conclusion that it is the nervous sytem where the changes need made.For this reason asana on it’s won may not deliver.You need other tools ,preferably effective ones .
Pushing and pulling can make muscles tighter- it belive it’s called the myotatic reflex. If the movment is initiated with awareness then that is different matter.Externally it’s pretty hard to meausre.
Adjustments in a yoga class is clearly an art and skill ,bold ones left to a fairly senior asana teacher.Adjustment iis coaxing and nudging in the right direction.But it is [U]your [/U]nervous sytem that does the real work.It’s amazing how many folk don’t seem to get this- i was one of them for quite some time wheni was intorduced to yoga.Merely excercising a muscle to push a bone one way does’nt usually work.This is where pranayam and meditative technqiues come in,when practicsed alongisde asana with balnced living and a reasonable sense of who you think you are(and your relationships) come to the rescue. I feel for most people this whole approach(ashtanga yoga, and i don’t mean patthabi jois )is a bit too radical.But i guess any entry point is such and the deeper we go within this vast territory the more progress we may begin to make.
Iused to think thesame as you- that wee need people outside of ourselves- to make changs- --yes i htink we do, but they cannot do your yoga for you.
Is it your motvation that is the stumbling block or is it asana (or both)?
And how loong have you practised asana?
If the mind is like an unruly elephant and the pranic body an angry snake then doing trikonasana or bend one lge over th other- asana, unless we have balnced mind and breath ,and open subtle and physical nerves, then attaining the goal of increased flexibility may be quite elusive and ephemeral.
In short-- try some other tools.A tool box just with asana in it is inadequateespecially if the horizon never seems to draw any closer.
In effective yoga—less is more ,and that applies to our effort and our applications.practice all 8 limbs-then try asana-your body and mind should be more open-you might be pleasantly suprised.I feel the first two limbs are imperative.
this is my take on it.
