Śrīmad-Bhāgavatam · Text 11.6.16
Who is speaking and story frame
त्वत्त: पुमान् समधिगम्य ययास्य वीर्यं
धत्ते महान्तमिव गर्भममोघवीर्य: ।
सोऽयं तयानुगत आत्मन आण्डकोशं
हैमं ससर्ज बहिरावरणैरुपेतम् ॥ १६ ॥
tvattaḥ pumān samadhigamya yayāsya vīryaṁ
dhatte mahāntam iva garbham amogha-vīryaḥ
so ’yaṁ tayānugata ātmana āṇḍa-kośaṁ
haimaṁ sasarja bahir āvaraṇair upetam
My dear Lord, the original puruṣa-avatāra, Mahā-Viṣṇu, acquires His creative potency from You. Thus with infallible energy He impregnates material nature, producing the mahat-tattva. Then the mahat-tattva, the amalgamated material energy, endowed with the potency of the Lord, produces from itself the primeval golden egg of the universe, which is covered by various layers of material elements.
