Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 21
Sanskrit:
चत्वार्येवेति तत्रापि तेज आपोऽन्नमात्मन: ।जातानि तैरिदं जातं जन्मावयविन: खलु ॥ २१ ॥
ITRANS:
catvāry eveti tatrāpiteja āpo ’nnam ātmanaḥjātāni tair idaṁ jātaṁjanmāvayavinaḥ khalu
Translation:
Some philosophers propose the existence of four basic elements, of which three — fire, water and earth — emanate from the fourth, the Self. Once existing, these elements produce the cosmic manifestation, in which all material creation takes place.
