The Third Limb: Asanas (Body postures)
Now here's one we know! Asana is the practice of physical postures. It is the most commonly known aspect of yoga for those unfamiliar with the other seven limbs of Patanjali’s Yoga Sutra. The practice of moving the body into postures has widespread benefits; of these the most underlying are improved health, strength, balance and flexibility. On a deeper level the practice of asana, which means "staying" or "abiding" in Sanskrit, is used as a tool to calm the mind and move into the inner essence of being. The challenge of poses offers the practitioner the opportunity to explore and control all aspects of their emotions, concentration, intent, faith, and unity between the physical and the ethereal body.
Practicing asana encourages a quieting of the mind, thus it becomes both a preparation for meditation and a meditation sufficient in and of itself. Releasing to the flow and inner strength that one develops brings about a profound grounding spirituality in the body.
The key to fostering expansion of awareness and consciousness begins with the control of breath, the fourth limb – Pranayama. Patanjali suggests that the asana and the pranayama practices will bring about the desired state of health; the control of breath and bodily posture will harmonize the flow of energy
"This limb of yoga practice reattaches us to our body. In reattaching ourselves to our bodies we reattach ourselves to the responsibility of living a life guided by the undeniable wisdom of our body."
