There are the obvious reason why yoga in its essence is balance, like the physical pose you stand in and balance your body in. Then there are the obvious but subtle things like your breath goes in and out and then in again, this is the balance in a dualistic sense. (Up and down, in and out.) Then there are the more subtle ways of balance, like how your eyes when they relax on a single point your breath becomes soft and your mind and your body stops moving because of your eyes not moving. (That was a silly twist of words.) Yoga is balance because no matter how you look at yoga it’s balanced. Yoga will grow confidence in the balance within yourself and will come strictly through the struggle of why you’re practicing for yourself in the first place. The struggle in the practice can lead a practitioner to a state of calm and effortlessness in mind and body, and this state of Self can be seen as a way to recognize what balance could be… The Balance of your mind body and spirit can be a personal choice, so always see it in your own way I’m sure you are balanced in your opinion, here. A struggle like reading this can increase your fight or flight response of your SNS (sympathetic nervous system) and now you can practice breathing to activate your PNS (parasympathetic nervous system) which will balance your mood. One last thought here, Yoga is a path to balance and your path to balance is infinite. Enjoy your breath.
