One might say, "Why must there be such a condition, why can it not be still?" Nothing living can be still. Can water be still? If it is still it is no more water. The water must rise and fall. Can air be still? If the air be still the end of the world will come. Can fire be still? If fire be still, it would be extinguished. Even the earth does not stand still, it allows the plants and trees to grow. Therefore the soul of the prophet, which must be life itself, cannot be in a still position. The consciousness must go higher, as high as possible, and then come down. And therefore this moving action will make the prophet say the word of God one moment and his own words the next. It is therefore that Muhammad knew the time when he was saying the word of God. And there were other times when he felt quite a human being, one like everybody, and what he said were words of wisdom, but he called them, "the words of the Prophet." And in this way the Hadith was distinguished from the Qu'ran.
