The Yoga Life--Meditation

Meditation is an integral part of yoga. That's because if we can't still the mind, it has control over us. Sometimes, we lose the use of an arm or a leg. Does that control us? No, we can will the mind to transcend physical limitations. Likewise, the mind doesn't control us (at least if we are aware of where the ultimate control lies--it's in the spirit). First and foremost, we are spirits. We just happen to live in a physical world in a physical body. But what makes us tick--move forward? What makes us go on when the mind and body are tired?
