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; nā haya - there is no; ullāsa - jubilation.

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.
