Question: When I run I sometimes get a slight knee pain. Should I stop running at that time?Sri Chinmoy: If you get just a slight pain in your knee, and if the pain is bearable, then you should continue running. At that time, feel that if you run a hundred metres more, the pain will go away. Then, after you have covered a hundred metres, feel that the pain will definitely stop if you run another hundred metres. If you do this five or six times, then most of the pain will go away. Even if some pain remains, the mind has already taken away your awareness from it. Your mind has forgotten about it. But if the pain is absolutely unbearable, what can you do? You simply have to surrender to it and stop running, at least for a while.
