Yours is top and undisclosed mystery. You are the foremost cause and supreme lord of this universe. You yourself are supreme god, Narayana, supreme soul (Paramatama) and Ishvara. You yourself are Sri Hari in the form of knowledge, the supreme shelter to the people desirous of emancipation, Vishnu. Gods even are alien to your real form. You yourself are beyond Puranas and supreme Purusha of Purana.
भूतात्मानं महात्मानमनन्तं विश्वतोमुखम्। अपि देवा न जानन्ति गुह्यमाद्यं जगत्पतिम्॥ नारायणं परं देवं परमात्मानमीश्वरम्। ज्ञानयोनि हरि विष्णुं मुमुक्षूणां परायणम्। परं पुराणं पुरुषं पुराणानां परं च यत्॥
