SUFISM AND PANTHEISM 25 R vt o 4 W . B V‘b advaitics compare things to pots of differing form but all made of clay, they are perfectly well aware of the inadequacy of such a picture.

On the contrary, he recognises innumerable levels of reality, the hierarchy of which is irreversible, so that one can affirm of the relative that it is in essence one with its principle,! or that it ““is’ its principle, although one can- not say of the principle that it is included in its product.
