The former explanation of the bird represents the idea of a soul whose dwelling-place is in heaven, and the latter that of the dweller on earth being capable of moving about in the higher spheres, and both these explanations give the idea that the spiritual man, dwelling on the earth, is from heaven; they explain also that the spiritual man is the inhabitant of the heavens and is dwelling on earth for a while.
