Question: Is the soul able to run the fastest with sound or with silence?Sri Chinmoy: If it is the Will of God then the soul can run the fastest with the help of silence, inner silence. Or if God wants, the soul can run the fastest with the help of sound. There is no hard and fast rule. Some people aspire through manifestation; other people manifest through aspiration. Here, sound is manifestation and silence is aspiration. In some cases God manifests Himself in and through those whom He has given the capacity to aspire. Again there are some people whom He has given the capacity to aspire through devoting themselves to the supreme cause of manifesting the Reality, the Source. A seeker can run the fastest when he has the capacity of both aspiration and manifestation. It is like having two legs: one leg is aspiration, another leg is manifestation. If one uses both legs, then naturally he will run faster, much faster than if he used only one leg.
