Undoubtedly, you come to hatha yoga to work with the physical postures, for that is the very definition of the practice. But why do you choose to work with the body? Is yoga a time-out from the rest of your life? Is it a kind of body-repair shop, as though your body was an automobile? Do you direct the body to yoga class because its health is necessary for the mind's well-being? Do you come to challenge the body because doing so stimulates your mind?
In your practice today, when you correct the position of your body in poses, remember to check in with your mind as well. If it has strayed from the practice, bring it back. Each time you do this, it will bring you closer to center, ease, and balance.
