Śrīmad-Bhāgavatam · Text 10.87.24
Who is speaking and story frame
क इह नु वेद बतावरजन्मलयोऽग्रसरं
यत उदगादृषिर्यमनु देवगणा उभये ।
तर्हि न सन्न चासदुभयं न च कालजव:
किमपि न तत्र शास्त्रमवकृष्य शयीत यदा ॥ २४ ॥
ka iha nu veda batāvara-janma-layo ’gra-saraṁ
yata udagād ṛṣir yam anu deva-gaṇā ubhaye
tarhi na san na cāsad ubhayaṁ na ca kāla-javaḥ
kim api na tatra śāstram avakṛṣya śayīta yadā
Everyone in this world has recently been born and will soon die. So how can anyone here know Him who existed prior to everything else and who gave rise to the first learned sage, Brahmā, and all subsequent demigods, both lesser and greater? When He lies down and withdraws everything within Himself, nothing else remains — no gross or subtle matter or bodies composed of these, no force of time or revealed scripture.
