Liberation from the desire for liberation breath technique. (An until-now unspoken secret technique)
1) Sit, stand, or lie down relatively comfortably.
2) Eyes can be open, closed, or partially closed.
3) Notice your breath, just as it is.
4) Notice your inability to notice the breath without changing it slightly.
5) Now try again to notice your breath without changing it.
6) Notice your inability to relinquish the need for control here.
Is there a technique you could learn, (though perhaps it would take much effort and many years to attain) to "not" control your breath? Or would this effort be yet another attempt to control?
The desire for control isn't voluntary, just as the beating of your heart isn't voluntary. In fact, most of "you" isn't voluntary. The you that seems to be able to take control is probably an artifact, or an epiphenomenon, of human consciousness. Your desire for control may assist some aspect of human life, though it may not actually work to control anything.
So, let's try one more time:
1)Notice your breath, in any way it appears, with as much or little control as you seem to be applying to it, and accept the situation, or don't accept it, as the case may be.
A more advanced practice is to go where people are and watch how they interact and multitask without voluntarily changing their breath, and how the breath is well-regulated to the task they are performing - how do they do it, you may ask!
Kidding aside, we often want to change ourselves for the better but we don't actually know how.
We don't know exactly what creates psychological/behavioural change, and we don't know what those changes we seem to desire would actually do to us if we could in fact change ourselves. There is a universe of unintended consequence for every "positive" change we could conceive.
Is it possible there is a deeper intelligence at work than our current desire for improvement? I don't mean an overseeing universal intelligence, more a recognition that everything that is going on backstage in our body and mind may be allowing us to "strut and fret our hour upon the stage" as Shakespeare said. The stage holds us up, provides the garments and the script so that we can immerse ourselves in the play and forget we alone didn't write the script. Maybe our ability to fundamentally change the story is a tale told by an idiot, full of sound and fury, signifying nothing.
