According to Moulana Roomi the mankind seek Allah who is the fountain- head of all beauty. (He sought multiplicity.) If people lay aside the veil of ignorance or materialism, they would find His manifestation within themselves.
Note: According to Moulana Roomi Allah displayed a mirror whose face was the human heart and whose back was the world. The heart is the citadel of spiritualism, and the world implies materialism, which acts as a veil against union with Allah.
آئینہ کر دم عیاں رویش دل و پستش جہاں،
پستش شود بہترز رو، گر توندانی روی را۔
(Roomi)
I displayed the mirror, its face was the heart and its back the world. Its back seems better if you fail to know its face (i.e. the heart which can receive the Divine manifestation.
جامۂ صد رنگ ازاں خم صفا،
سادہ ویک رنگ گشتی چوں ضیا۔
(Roomi)
Even as a multi-coloured garment, if you get into the jar of transparence, you will come out very plain and colourless like light.

Roomi said all seek Beauty's source,
From your heart, veil remove and vision
beautific behold.

Seekers are numerous, fountainhead of beauty is one, this Rumi has said,
If you uncover your inner self, you will perceive him inside you.
