caitanya-prabhura - of Lord Śrī Caitanya Mahāprabhu; ei - this; kṛpāra mahimā - the glory of the mercy; brahmā-ādi - headed by Lord Brahmā; deva - the demigods; yāra - of which; nāhi pāya - do not reach; sīmā - the limit.

This is the glory of Śrī Caitanya Mahāprabhu’s causeless mercy, which even the demigods, headed by Lord Brahmā, cannot estimate.
