I discovered the word equanimity a few years ago and find that the state it describes, feeling calm amidst chaos, is so key to my gaining a sense of security. And regaining it.

And regaining it and.....
I find Yoga is a great way to practice that feeling and have support doing so.
Teachers vary greatly and I find I really like the kind and
attentive ones. There are teachers who really pay attention to each student and kindly assist the student in holding a position in such a way that works for that particular student. I like that attention and I like feeling that I am in a setting where others are getting that care too. I feel like it is some sort of metaphor for taking turns and for what a supportive family would feel like, i would feel like in a supportive family.
I also learned to focus inward more through yoga and not be quite so reactive to things and people around me. Many teachers really
encourage students to not make comparisons to others in class and to
focus on their own breathing and what their unique flexibility, strength and body shape does (or doesn't). I find the calmness and awareness help me throughout the day to respond rather than react - just the sort of subtle adjustment that in yoga I've learned brings major results.
In yoga I learn to breath and to notice when I am not...I'd been holding my breath most of my life but didn't know anything else. Didn't know what I was missing. I hear my own voice and learn to just listen without judging. Teachers incourage students to listen, to feel in an intimate and intricate way in the moment.
In yoga
I learn to make sounds and not feel like I am taking up the airwaves but instead that I am just being with others who are just being and there are enough airwaves for everyone. I mean I know that is true intellectually yet in Yoga I feel it is true. Yoga teachers encourage students to breath and to make a sound when breathing and sometimes they encourage a meditation "om" sound.
