īśvara-purīra śiṣya — brahmacārī kāśīśvara śrī-govinda nāma tāṅra priya anucara
Brahmacārī Kāśīśvara was a disciple of Īśvara Purī, and Śrī Govinda was another of his dear disciples.
Purport
Govinda was the personal servant of Śrī Caitanya Mahāprabhu. In the Gaura-gaṇoddeśa-dīpikā (137) it is stated that the servants formerly named Bhṛṅgāra and Bhaṅgura in Vṛndāvana became Kāśīśvara and Govinda in Caitanya Mahāprabhu’s pastimes. Govinda always engaged in the service of the Lord, even at great risk.
