Śrīmad-Bhāgavatam · Text 11.28.19
Who is speaking and story frame
यथा हिरण्यं स्वकृतं पुरस्तात्
पश्चाच्च सर्वस्य हिरण्मयस्य ।
तदेव मध्ये व्यवहार्यमाणं
नानापदेशैरहमस्य तद्वत् ॥ १९ ॥
yathā hiraṇyaṁ sv-akṛtaṁ purastāt
paścāc ca sarvasya hiraṇ-mayasya
tad eva madhye vyavahāryamāṇaṁ
nānāpadeśair aham asya tadvat
Gold alone is present before its manufacture into gold products, the gold alone remains after the products’ destruction, and the gold alone is the essential reality while it is being utilized under various designations. Similarly, I alone exist before the creation of this universe, after its destruction and during its maintenance.
