Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 11
Sanskrit:
मृगतृष्णां यथा बाला मन्यन्त उदकाशयम् ।एवं वैकारिकीं मायामयुक्ता वस्तु चक्षते ॥ ११ ॥
ITRANS:
mṛga-tṛṣṇāṁ yathā bālāmanyanta udakāśayamevaṁ vaikārikīṁ māyāmayuktā vastu cakṣate
Translation:
Just as men of childish intelligence consider a mirage in the desert to be a pond of water, so those who are irrational look upon the illusory transformations of Māyā as substantial.
