Yoga is an ancient science that deals with the link between the body and the mind, the physical and the metaphysical, the self and the universal. It teaches you the art of mind control, physical fitness, and mental & emotional equipoise. This is done through techniques that enhance energy flow and cleanse the system, thus ridding ,both, the body and the mind of toxins that lead to fatigue, stress and disease.
Asanas are physical postures that work on the internal machinery of the whole body. The internal organs are massaged through these various postures and are stimulated, thereby functioning more efficiently. As yoga postures are always practiced with deep breathing, they also help to relax, increase concentration skills and develop mental equi-poise.
Pranayama is that branch of yoga which deals with the science of breath, and its control. Prana, or vital air in the body of the individual is a part of universal air. The regulation of breath helps the yogi to regulate and steady the mind. Pranayama or yogic breathing directly affects the blood circulatory system, the endocrine system and the nervous system. All diseases of the body can be destroyed at the root by controlling and regulating prana.
Mind is the product of thoughts which are difficult to restrain for they are subtle and fickle. A thought that is well guarded by a controlled mind brings peace of mind and happiness. Dhyan or meditation is that branch of yoga that deals with the art of learning how the mind works and thus how one can control it, rather than be controlled by it.
Kriyas are internal and external yogic techniques using Mudras (acupressure points), Bandhas (internal muscular movements) and cleansing exercises (Rete or Nasal cleansing, Dhanti etc..) that service & overhaul the body machinery and re-energizing the whole system.
