Śrīmad-Bhāgavatam · Text 10.51.50
Who is speaking and story frame
पुरा रथैर्हेमपरिष्कृतैश्चरन्
मतंगजैर्वा नरदेवसंज्ञित: ।
स एव कालेन दुरत्ययेन ते
कलेवरो विट्कृमिभस्मसंज्ञित: ॥ ५० ॥
purā rathair hema-pariṣkṛtaiś caran
mataṁ-gajair vā nara-deva-saṁjñitaḥ
sa eva kālena duratyayena te
kalevaro viṭ-kṛmi-bhasma-saṁjñitaḥ
The body that at first rides high on fierce elephants or chariots adorned with gold and is known by the name “king” is later, by Your invincible power of time, called “feces,” “worms,” or “ashes.”
