"abhyasa vairagyabhyam tannirodhah" YSP 1.12 Practice and detachment are the means to still the movements of the consciousness." B.K.S. Iyengar - Anything worth doing takes time, focus yourself on a long consistent yoga practice. Initially your focus will be on learning the proper actions but once you have been through the postures a few hundred or even thousands of times you will begin to see so much more than what you intially understood about the pose.
Do not let your mind talk you out of practicing. One hurdle to get past is participating and practicing regularly, your mind will play tricks on you and this is a big step in your journey. Start by committing to go to class even if you don't feel like it and for the days you can't make class, practice at home. Make time to practice your poses even if all you have is 15 minutes, most important is a regular consistent practice and with this you will start to understand more about yourself.
With a consistant yoga practice you will begin to gain knowledge of any imbalances in your body from right to left or even from your front body in comparison to your back side. You start to recognize how you use one muscle too much and then some muscles are completely turned off or inhibited. With this new knowledge of how your body works your mind will create new connections which allows you to begin to have a deeper understanding into your personal patters which will translate directly into your relationship with yourself as well as others.
This Self-Knowledge you gain from a long consistant practice will give you the tools to change life patters and with new understanding detachment will come. After practicing for a period of time you will have glimpses of pure consciousness in comparison to fluctuations in consciousness and once you have touched a moment of this pure bliss state you will find yourself wanting to make your way back to the stillness. In this place you are able to let go of what you do not understand along with any expectations so you can look at what you do know to see clearly how to be present.
