Hazrat Inayat Khan:

Many intellectual people, with their various ideas, differ from one another in their opinions and in their way of looking at things, in their speculations, but do the prophets differ from one another? No, they cannot differ. The reason is that it is the various minds which differ, not the souls. The one who lives in his mind, is conscious of his mind; the one who lives in his soul is conscious of the soul.
