The impossible remains impossible to all men. Exceptional people find it possible. He who seeks the Spirit truthfully becomes that rare exception. My impossibilities are realities in life. A half-starved, last grade servant seven years after retirement hospitalised and kept alive on oxygen, especially when it is the third attack, does not consider survival possible. To him it is a real impossibility, even it thought. What is impossible for one in unhelpful circumstances is possible for another in supportive, affluent circumstances. To the former it remains impossible.
To plough deeper than six inches is not possible for the country plough, but is possible for the tractor. A powerful tractor can plough three feet deep. The change of the instrument changes the result. We know the physical man whose only instruments are his hands and legs cannot understand law or medicine, but the educated mental man can. Mind is a superior instrument which makes what is impossible for the physical man possible. The Spirit is far superior instrument which makes possible what is impossible to the mental man.
The Spirit is there in every one of us. Our tradition has not taught us to rely on it in our daily lives except through worship. Worship will reach the Spirit in the rare few in moments of crisis. To believe in the Spirit inside is itself the beginning of such an invocation. One can feel greater energy or an inspired enthusiasm when the mind turns to the Spirit. To see the extraordinary power of Spirit in everyday activities is possible for us.
