Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 7
Sanskrit:
स्नेहाधिष्ठानवर्त्यग्निसंयोगो यावदीयते ।तावद्दीपस्य दीपत्वमेवं देहकृतो भव: ।रज:सत्त्वतमोवृत्त्या जायतेऽथ विनश्यति ॥ ७ ॥
ITRANS:
snehādhiṣṭhāna-varty-agni-saṁyogo yāvad īyatetāvad dīpasya dīpatvamevaṁ deha-kṛto bhavaḥrajaḥ-sattva-tamo-vṛttyājāyate ’tha vinaśyati
Translation:
A lamp functions as such only by the combination of its fuel, vessel, wick and fire. Similarly, material life, based on the soul’s identification with the body, is developed and destroyed by the workings of material goodness, passion and ignorance, which are the constituent elements of the body.
