Yoga teaches many physical movements, breathing techniques and spiritual practices that require yogis to observe large and small concepts and physical movements. Alpa, when added to the name of an asana or pranayama, directs the yogi to make small movements and small breaths. When alpa is added to a Sadhana, or daily practice, it means, "to take or do less." For instance, alpanidra means "sleep less" and alpaahar means "eat less." In this way alpa can guide the yogi to live a moderate life.
