Śrī Caitanya Caritamrta · Text Ādi 5.124
এত মূর্তিভেদ করি’ কৃষ্ণসেবা করে ।
কৃষ্ণের শেষতা পাঞা ‘শেষ’ নাম ধরে ॥ ১২৪ ॥
eta mūrti-bheda kari’ kṛṣṇa-sevā kare
kṛṣṇera śeṣatā pāñā ‘śeṣa’ nāma dhare
He is thus called Lord Śeṣa, for He has attained the ultimate end of servitude to Kṛṣṇa. He takes many forms for the service of Kṛṣṇa, and thus He serves the Lord.
