All types of yoga and mediation build awareness to important principles. There are the eight limbs of yoga (wiki), including the Yamas - nonviolence, truth in word and thoughts, non-covetousness, etc - and the Niyamas - satisfaction, cleanliness of mind and body, etc. In Vipassana meditation, the ten parami or perfections guide the practice and practitioner. These examples are from my primary practices and probably have commonalities with many Eastern and spirituality oriented philosophies. Even when yoga is without Savasana or calming effects, the possibility for an individual to open their minds to seeking other yoga styles, become aware of the breath, and start to live healthier lives are enough to encourage the growth of yoga. Physical and behavior changes are the gateway to altering mental processes and perceptions.
The advent of "commercialized" yoga is a way to plant a seed of interest in bridging physical and mental health benefits of yoga and meditation. Yoga in any form promotes the eight limbs of yoga or perfections. Tying the benefits gained on the yoga mat to the real world is not necessarily a natural or self-directed process. Guidance for your physical practice is accessible on the Internet and books. The step by step instructions for poses are easier to follow than philosophical discourse. Explicitly connecting the dots between the babbles of your yoga teacher about love, compassion, and nonviolence with real world areas of your life is helpful to answer: Why you continue doing yoga and possibly seeking more about the practice?
