Pranayama (breathing techniques)The Pranayama in Yoga is to master ones' breathing patterns. If one can master breath, then the mastery of mind is within reach. Through breathing excercises the flow of prana or vital life force through the body is regulated.
To boost your energy levels, there is no better way than the regular practice of yogic breathing exercises (pranayamas). These exercises have been developed and perfected over thousands of years to bestow their powerful benefits, so if you are looking for more vitality and energy, I strongly recommend establishing a regular, daily pranayama practice.
