Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 28

Sanskrit:

एको मयेह भगवान्विविधप्रधानै-श्चित्तीकृत: प्रजननाय कथं नु यूयम् ।अत्रागतास्तनुभृतां मनसोऽपि दूराद्ब्रूत प्रसीदत महानिह विस्मयो मे ॥ २८ ॥

ITRANS:

eko mayeha bhagavān vividha-pradhānaiścittī-kṛtaḥ prajananāya kathaṁ nu yūyamatrāgatās tanu-bhṛtāṁ manaso ’pi dūrādbrūta prasīdata mahān iha vismayo me

Translation:

I called for the Supreme Personality of Godhead, desiring a son like Him, and I thought of Him only. But although He is far beyond the mental speculation of man, all three of you have come here. Kindly let me know how you have come, for I am greatly bewildered about this.

Purport:

Atri Muni was confidently aware that the Supreme Personality of Godhead is the Lord of the universe, so he prayed for the one Supreme Lord. He was surprised, therefore, that three of them appeared.
