A beginner's mind.
Every time you step onto your mat, every time you interact with someone, every time you head into the world and take a deep breath is an opportunity to practice, and opportunity to let go and to open your mind to the possibilities.
It doesn’t matter if you have never practiced Yoga before, or if you are a longtime practioner, once you take a step onto your mat it is a new experience. With a beginners mind you have no expectation, you can be open to whatever the experience provides you. The longer I have been practicing Yoga, the more humble I become.
