CC Adi 5.78
- yadyapi kahiye tāṅre kṛṣṇera ‘kalā’ kari
- matsya-kūrmādy-avatārera tiṅho avatārī
yadyapi—although; kahiye—I say; tāṅre—to Him; kṛṣṇera—of Lord Kṛṣṇa; kalā—part of the part; kari—making; matsya—the fish incarnation; kūrma-ādi—the tortoise incarnation and others; avatārera—of all these incarnations; tiṅho—He; avatārī—the original source.
Although Kāraṇodaśāyī Viṣṇu is called a kalā of Lord Kṛṣṇa, He is the source of Matsya, Kūrma and the other incarnations.
