CC Madhya 8.28

ei-mata vipra-gaṇa bhāve mane mana
vijātīya loka dekhi, prabhu kaila samvaraṇa
Word for word: 
ei-mata — in this way; vipra-gaṇa — all the brāhmaṇas; bhāve — think; mane mana — within their minds; vijātīya loka — outside people; dekhi — seeing; prabhu — Lord Caitanya Mahāprabhu; kaila — did; samvaraṇa — restraining.
Translation: 
While the brāhmaṇas were thinking in this way about the activities of Śrī Caitanya Mahāprabhu and Rāmānanda Rāya, Śrī Caitanya Mahāprabhu saw those outsiders and restrained His transcendental emotions.
Purport: 

Rāmānanda Rāya was intimately related to Śrī Caitanya Mahāprabhu; therefore he can be accepted as a sajātīya, a person within the intimate circle of the Lord. The brāhmaṇas, however, were followers of the Vedic rituals and were not able to have an intimate connection with Śrī Caitanya Mahāprabhu. Consequently they are called vijātīya-loka. In other words, they were not pure devotees. One may be a highly learned brāhmaṇa, but if he is not a pure devotee he is a vijātīya, an outcaste, one outside devotional service — in other words, a nondevotee. Although Śrī Caitanya Mahāprabhu and Rāmānanda Rāya were embracing in ecstasy, the Lord restrained His transcendental emotions upon seeing the outsider brāhmaṇas.
