The philosophy of yoga is mainly the literal meaning of the coordination of two existences and the word yoga also has two meanings: first joint and second samadhi. Yoga is a five thousands year old style of Indian wisdom and is the science of living. Maharishi Patanjali originated from the Yogasutra of Maharishi Patanjali in the second century BCE and originated from the Sanskrit root word YUJ (YUJA). Yuj means - to unite or unite each other. The yoga of Maharishi Patanjali is called Raj Yoga or Ashtanga Yoga. The above eight organs (1) Yama (2) Niyam (3) Asana (4) Pranayama (5) Pratyahara (6) Dharna (7) Dhyana (8) Samadhi includes all types of yoga. Human can achieve liberation by using techniques of physical application and compound meditation, and thus man becomes separated from nature. But until you connect with yourself, it will be difficult to reach samadhi.
