According to mahrshi Patanjali yoga is the state of meditation in which a person is capable to observe the whole universe with his power of imagination. He said that through meditation a person can see in Manastatva and can explore the mysteries of universe. And believe me friend I my self tried it and somewhere it’s true. The definition of yoga taught to us from you childhood is not correct. You will get to know about reality when you have your own questions on every answer. I hope you like it. Thank you!!!
