acarya-sambandhe bahye kare prityabhasa
krsna-bhakti vina prabhura na haya ullasa
acarya-sambandhe—because he was related with Bhagavan Acarya; bahye—externally; kare—does; priti-abhasa—appearance of pleasure; krsna-bhakti—devotional service to Lord Krsna; vina—without; prabhura—of Sri Caitanya Mahaprabhu; na haya—there is no; ullasa—jubilation.
Sri Caitanya Mahaprabhu derives no happiness from meeting one who is not a pure devotee of Krsna. Thus because Gopala Bhattacarya was a Mayavadi scholar, the Lord felt no jubilation in meeting him. Nevertheless, because Gopala Bhattacarya was related to Bhagavan Acarya, Sri Caitanya Mahaprabhu feigned pleasure in seeing him.
