namaḥ oṁ viṣṇu-pādāya śrī gaura-priya mūrtaye
śrīmate bhakti-vallabh tīrtha gosvāmī nāmine

māyāvāda-vikhandanaṁ gurorvanyanukīrtanaṁ

“I pay my respectful obeisances unto Oṁ Viṣṇupād Śrī Śrila Bhakti Ballabh Tīrtha
Gosvāmī Mahārāj, who is the very dear associate of Śrī Gaura-sundar.

He cuts to pieces the false doctrine of māyāvada and repeats the divine words of his spiritual master. He is
preaching even in the western countries and his face is always smiling blissfully.

Like Bhagirath Mahārāj brought the holy Gaṅgā, he brought the Gaṅgā of pure devotion to all
people, and he is non-different from Śrila Bhakti Dayita Mādhava Gosvāmī Mahārāj.

I pay my respectful obeisances unto him who teaches through his perfect example, is expert in relishing the nectar of chanting the Holy Name, and is distributing that nectar to others. He is the personification of Kṛṣṇa’s mercy and Vedic knowledge descending in disciplic succession.

I pay my humble obeisances unto that great personality Śrīla Bhakti Ballabh Tīrtha Gosvāmī Mahārāj, who preaches the Holy Name of Gaurāṅga with a soft
heart filled with nectar, who always hankers for the service of the devotees and who has pure love and affection for his God-brothers.”
