In one variation, the rechak (exhaled air), poorak (inhalation) and kumbhak (retention during normal inhaling and exhaling) are the three parts of the breath that are regulated. Pranayama is practiced to develop mental, physical and spiritual strength

Asanas teach poise, balance and strength and are practiced to improve the body’s physical health and clear the mind in preparation for meditation.
