In Śrīmad-Bhāgavatam (10.46.31) it is said that Balarāma and Kṛṣṇa are the origin of all living entities and that these two personalities enter into everything. A list of incarnations is given in Śrīmad-Bhāgavatam (1.3), and they are as follows: (1) the Kumāras, (2) Nārada, (3) Varāha, (4) Matsya, (5) Yajña, (6) Nara-Nārāyaṇa, (7) Kārdami Kapila, (8) Dattātreya, (9) Hayaśīrṣa, (10) Haṁsa, (11) Dhruvapriya, or Pṛśnigarbha, (12) Ṛṣabha, (13) Pṛthu, (14) Nṛsiṁha, (15) Kūrma, (16) Dhanvantari, (17) Mohinī, (18) Vāmana, (19) Bhārgava (Paraśurāma), (20) Rāghavendra, (21) Vyāsa, (22) Pralambāri Balarāma, (23) Kṛṣṇa, (24) Buddha and (25) Kalki. Because almost all of these twenty-five līlā-avatāras appear in one day of Brahmā, which is called a kalpa, they are sometimes called kalpa-avatāras. Out of these incarnations, Haṁsa and Mohinī are not permanent, but Kapila, Dattātreya, Ṛṣabha, Dhanvantari and Vyāsa are five eternal forms, and they are more celebrated. Kūrma (the tortoise incarnation), Matsya (the fish), Nara-Nārāyaṇa, Varāha (the boar), Hayaśīrṣa, Pṛśnigarbha and Balarāma are considered incarnations of vaibhava. Similarly, there are three guṇa-avatāras, or incarnations of the qualitative modes of nature, and these are Brahmā, Viṣṇu and Śiva.
There are fourteen manvantara-avatāras: (1) Yajña, (2) Vibhu, (3) Satyasena, (4) Hari, (5) Vaikuṇṭha, (6) Ajita, (7) Vāmana, (8) Sārvabhauma, (9) Ṛṣabha, (10) Viṣvaksena, (11) Dharmasetu, (12) Sudhāmā, (13) Yogeśvara and (14) Bṛhadbhānu. Out of these fourteen manvantara-avatāras, Yajña and Vāmana are also līlā-avatāras. The manvantara-avatāras are also known as vaibhava-avatāras.
The four yuga-avatāras are also described in Śrīmad-Bhāgavatam. In the Satya-yuga the incarnation of God is white; in the Tretā-yuga He is red; in the Dvāpara-yuga He is blackish; and in the Kali-yuga He is also blackish, but sometimes, in a special Kali-yuga, His color is yellowish (as in the case of Caitanya Mahāprabhu). As far as the śaktyāveśa-avatāras are concerned, they include Kapila, Ṛṣabha, Ananta, Brahmā (although sometimes the Lord Himself becomes Brahmā), Catuḥsana (the Kumāras, who are the incarnation of knowledge), Nārada (the incarnation of devotional service), King Pṛthu (the incarnation of administrative power) and Paraśurāma (the incarnation who subdues evil principles).
