CC Antya 2.91

ācārya-sambandhe bāhye kare prītyābhāsa
kṛṣṇa-bhakti vinā prabhura nā haya ullāsa
Word for word: 
ācārya-sambandhe — because he was related with Bhagavān Ācārya; bāhye — externally; kare — does; prīti-ābhāsa — appearance of pleasure; kṛṣṇa-bhakti — devotional service to Lord Kṛṣṇa; vinā — without; prabhura — of Śrī Caitanya Mahāprabhu; haya — there is no; ullāsa — jubilation.
Translation: 
Śrī Caitanya Mahāprabhu derives no happiness from meeting one who is not a pure devotee of Kṛṣṇa. Thus because Gopāla Bhaṭṭācārya was a Māyāvādī scholar, the Lord felt no jubilation in meeting him. Nevertheless, because Gopāla Bhaṭṭācārya was related to Bhagavān Ācārya, Śrī Caitanya Mahāprabhu feigned pleasure in seeing him.
