Question: Can weightlifting develop inner strength?
Sri Chinmoy: No, weightlifting cannot. Inner strength is a totally different matter. For that you need aspiration, the heart's inner cry. Otherwise, you can be physically very strong, but inwardly, spiritually, you can be the weaker than the weakest human being.
