Śrī Caitanya Caritamrta · Text Ādi 5.78
যদ্যপি কহিয়ে তাঁরে কৃষ্ণের ‘কলা’ করি ।
মৎস্য–কূর্মাদ্যবতারের তিঁহো অবতারী ॥ ৭৮ ॥
yadyapi kahiye tāṅre kṛṣṇera ‘kalā’ kari
matsya-kūrmādy-avatārera tiṅho avatārī
Although Kāraṇodaśāyī Viṣṇu is called a kalā of Lord Kṛṣṇa, He is the source of Matsya, Kūrma and the other incarnations.
