Srimad Bhagavatam Canto 03, Chapter 07, Text 08

SB 3.7.8

sri-suka uvaca
sa ittham coditah ksattra
 tattva-jijñasuna munih
pratyaha bhagavac-cittah
 smayann iva gata-smayah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Sri Sukadeva Gosvami said: O King, Maitreya, being thus agitated by the inquisitive Vidura, at first seemed astonished, but then he replied to him without hesitation, since he was fully God conscious.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Since the great sage Maitreya was filled with God consciousness, he had no reason to be astonished at such contradictory questions by Vidura. Therefore, although as a devotee he externally expressed surprise, as if he did not know how to reply to those questions, he immediately became perfectly settled and properly replied to Vidura. Yasmin vijñate sarvam evam vijñatam bhavati (Mundaka Upanisad 1.3). Anyone who is a devotee of the Lord knows about the Lord to some extent, and devotional service to the Lord makes him able to know everything by the grace of the Lord. Although a devotee may apparently express himself to be ignorant, he is full of knowledge in every intricate matter.
