As much as we need sensation in life to make our experience of life concrete, so much or even more do we need exaltation in order to live life fully. The lower creation such as birds and beasts also have glimpses of exaltation. They do not only rejoice in grazing and in finding seeds, in making nests or in playing in the air, in singing and in running about in the forest. There are moments when even birds and beasts feel exaltation. And if we go into this subject more deeply we shall understand what we read in a most wonderful verse of Islamic tradition: "There are moments when even rocks become exalted and trees fall into ecstasy." If that be true, then man, who is created to complete the experience that any living being can have, must experience exaltation as much as he experiences sensation.
