"Yoga is the union of the individual soul with the divine soul. Holy men & women throughout history have sought a deeper understanding of consciousness in harmony and communion with the universal laws of nature. In states of bliss-consciousness, they designed powerful techniques that benefit humanity on the physical, mental and spiritual levels. These techniques form the basis of the 8 limbs or aspects of Yoga practice that we know today.
The third limb of Yoga, Asana, or postures, is often the starting point for many who are new to this practice. Unlike ordinary exercises, yoga develops far more than just the physical body. As students first practice postures, they gradually unleash the life force and begin to experience the spirit more directly. This starts to effect positive changes in their lives that are reinforced through the experience of regular practice.
The postures are very important, but they are only one of the 8 limbs of practice, designed mainly to prepare the body for breathing exercises and meditation. In order to find a true union with the Divine you must surrender your goals to a higher spirit; only then will you be able to go beyond the individual mind and join in the great ocean of consciousness, entering the temple that is within you own heart."
