In Patanjali's Yoga Sutra, the eightfold path is called ashtanga, which literally means "eight limbs" (ashta=eight, anga=limb). These eight steps, commonly known as the 8 limbs of yoga, basically act as guidelines on how to live a meaningful and purposeful life. They serve as a prescription for moral and ethical conduct and self-discipline; they direct attention toward one's health, and they help us to acknowledge the spiritual aspects of our nature.
