What is Yoga

 Way to feel your link with Him - Guru Mantra. "Suppose, there is a drop of water in an ocean. When the drop feels its unity with the ocean, the drop no longer remains as a drop, it becomes the ocean. But when it feels its separation from the ocean, it is nothing but a drop of water. So, when a human being feels his/her unity with the Supreme Lord and feels that he/she is not an ordinary person, but the blessed child of the Supreme Father and when becomes one with him, then he/she is no longer an ordinary person. He/she acquires immense power, immense vitality, infinite vitality and this is your Yoga in the physical sphere. You should always remember that a man or a woman is an ordinary person when separated from the Supreme Father, but he/she becomes Supreme when one with the Supreme. This we do with the help of our Guru Mantra. This is Yoga in the physical sphere."
