ithe - for this reason; bhakta-bhāva - the ecstasy of a devotee; dhare - accepts; caitanya - Lord Caitanya Mahāprabhu; gosāñi - the transcendental teacher; bhakta-svarūpa - exactly like a pure devotee; tāṅra - His; nityānanda - Lord Nityānanda; bhāi - brother.

For this reason Śrī Caitanya Mahāprabhu, the supreme teacher, accepts the form of a devotee and accepts Lord Nityānanda as His elder brother.
