Intelligence becomes intelligible by turning into denseness; that denseness being manifest to its own view, creates two objects: Zat, the self, and Sifat, what is known by the self. And then comes of necessity a third object, the medium by which the self knows what it knows: Nazar, the sight or the mind. The Sufi poets have pictured these three in their verse as Bagh, Bahar, and Bulbul, the garden, the spring, and the nightingale. And it is these three aspects of life which are at the root of the idea of Trinity. The moment these three are realized as one, life's purpose is fulfilled.
