Yoga is a five thousand year old style of Indian wisdom and is the science of living. Maharishi Patanjali originated the Yogasutra from the Sanskrit word YUJ- means to combine or unify each other. He described the Yoga as Rajyoga or Ashtangayoga. Yoga consists of eight organs i). Yama, ii). Niyam, iii). Asana, iv). Pranayamas, v). Pratyahara, vi). Dharana, vii). Dhyan and viii). Samadhi. By using physical application and meditation of compound techniques man becomes separated from the nature, but until we connect ourselves, it will be difficult to reach samadhi. Yoga is not only physical and breathing exercises of the body - but with performing yogasanas, pranayama and meditation, the body remains perfectly healthy. Patanjali's Yogasutra focused on finding simple but profound yoga principles of (Yama and Niyam), which can become the essence of a happy and healthy life for us. The contentment principle (Niyam) helps in being satisfied in life and imperfection theory in relieving anxiety, distraction and stress due to greed and attachment. The defecation principle describes mental and physical purification. Thus these rules make life more meaningful by adopting scientific methods.
