It is very necessary to keep the body fit. Yoga can help you with this. But what is the parameter of a fit body? I got to know today that the insurance company would not give me insurance because according to my height I am not weighing enough. I feel healthy, I feel fit! I have never been ill. But the German system has another view of it. According to their standard I am missing 8 Kilos. But this is German standard, not yogic standard! I said I am sorry, I cannot gain 8 Kilo weight.
So what I want to say is that it does not really matter, how much you weigh. I doesn't matter if it is less or medium or much. But how do you feel inside? It is about your feelings! You have to feel well in your body. If you are happy with your body you will be healthy.
