For many yogis, meditation and yoga go hand in hand. Why? Because both practices involve a silent way of looking at resistance. In yoga, poses are used to help a person get into the body and relax. In doing so, stored energetic trauma is freed. With meditation, a person is given an opportunity to be with the resistance. By not pushing it away or trying to define it, resistance passes.
In this Gaiam interview with Rodney Yee, yoga as a natural bridge to meditation is explored. According to Yee, while meditation and yoga hold within them the ability to transcend resistance, imperative is the use of a person’s breath to help facilitate an awareness of the body and mind.
The breath itself, as the yogis have said for thousands of years, is the ruler of the mind and body. If you control the breath, in some sense you also control the state of the mind and the chemistry of the body. By making the breath smooth and easy, you create a quiet, easy mind. Breath is what stills and quiets the mind so that meditation can take place, and relaxation is a fundamental aspect of breath.
