CC Adi 7.12
- ithe bhakta-bhāva dhare caitanya gosāñi
- ‘bhakta-svarūpa’ tāṅra nityānanda-bhāi
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.
