CHĀNDOGYA UPANISHAD · 6.2.4

ता आप ऐक्षन्त बह्व्यः स्याम प्रजायेमहीति ता
अन्नमसृजन्त तस्माद्यत्र क्व च वर्षति तदेव भूयिष्ठमन्नं
भवत्यद्भ्य एव तदध्यन्नाद्यं जायते ॥ ६.२.४॥

tā āpa aikṣanta bahvyaḥ syāma prajāyemahīti tā
annamasṛjanta tasmādyatra kva ca varṣati tadeva bhūyiṣṭhamannaṃ
bhavatyadbhya eva tadadhyannādyaṃ jāyate ॥ 6.2.4॥

'Water thought, may I be many, may I grow forth. It sent forth earth (food). 'Therefore whenever it rains anywhere, most food is then produced. From water alone is eatable food produced.
