Practicing yoga is like tuning up your car: it allows the bode to function in accordance with what it was designed to do.
Yoga adds years to your life and life to your years.
You are not your thoughts, and you are not the product of your thoughts.
When you know who you truly are, you can live more freely and in tune with your karma.
If you don't have the background awareness of oneness, duality becomes real.
A guru is needed not to worship, but to direct you.
