Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 6

Sanskrit:

कन्योपगूढो नष्टश्री: कृपणो विषयात्मक: ।नष्टप्रज्ञो हृतैश्वर्यो गन्धर्वयवनैर्बलात् ॥ ६ ॥

ITRANS:

kanyopagūḍho naṣṭa-śrīḥkṛpaṇo viṣayātmakaḥnaṣṭa-prajño hṛtaiśvaryogandharva-yavanair balāt

Translation:

When King Purañjana was embraced by Kālakanyā, he gradually lost all his beauty. Having been too much addicted to sex, he became very poor in intelligence and lost all his opulence. Being bereft of all possessions, he was conquered forcibly by the Gandharvas and the Yavanas.

Purport:

When a person is attacked by the invalidity of old age and is still addicted to sense gratification, he gradually loses all his personal beauty, intelligence and good possessions. He thus cannot resist the forceful attack of the daughter of Time.
