Sir Muhammad Iqbal,
The Development of Metaphysics in Persia
“ Regarded as an essence, therefore, the Real is one. But it is also many, from a different standpoint. It is life, power, love; though we cannot say that these qualities inhere in it—they are it, and it is them. Unity does not mean oneness, its essence consists in the "dropping of all relations." Unlike the Ṣūfīs and other thinkers, Mulla Hādī holds and tries to show that belief in multiplicity is not inconsistent with belief in unity; since the visible "many" is nothing more than a manifestation of the names and attributes of the Real. ”
