Blended reading (Sanskrit + English inline)
jaya jaya mahāprabhu śrī-kṛṣṇa-caitanya tāṅhāra caraṇāśrita, sei baḍa dhanya
Let me offer glorification to the Supreme Lord Śrī Caitanya Mahāprabhu. One who has taken shelter of His lotus feet is the most glorified person.
Purport
Prabhu means master. Śrī Caitanya Mahāprabhu is the supreme master of all masters; therefore He is called Mahāprabhu. Any person who takes shelter of Śrī Kṛṣṇa Caitanya Mahāprabhu is most glorified because by the mercy of Śrī Caitanya Mahāprabhu he is able to get promotion to the platform of loving service to the Lord, which is transcendental to salvation.
— A.C. Bhaktivedanta Swami Prabhupāda
