Come to Omega's 2008 Being Yoga conference and learn to live your yoga by combining yoga's physical and spiritual ideals with seva, or "selfless service."
The great spiritual treatise, the Bhagavad Gita, speaks to the notion of Karma Yoga, or the yoga of selfless action. Since we cannot live without action, the Bhagavad Gita teaches, then our actions should be for the benefit of others.
