The Personality of Godhead Lord Viṣṇu has appeared in various partial incarnations for the benefit of the entire world and has given instructions in spiritual knowledge in the forms of Haṁsa, Dattātreya, Sanaka and the other Kumāra brothers, and Ṛṣabhadeva. In the form of Hayagrīva He killed the demon Madhu and saved all the Vedas. In the avatāra of Matsya, the fish, He protected both the earth and Satyavrata Manu. In the incarnation of Varāha, the boar, He delivered the earth and destroyed Hiraṇyākṣa; in that of Kūrma, the tortoise, He carried Mandara Mountain upon His back; and in the form of Śrī Hari He gave liberation to the king of the elephants. The Lord delivered the Vālakhilyas, who had been trapped in the water in a cow’s hoofprint, He delivered Indra from the reaction for murdering a brāhmaṇa, and He delivered the wives of the demigods from imprisonment in the palaces of the demoniac asuras. In the avatāra of Nṛsiṁha, He killed Hiraṇyakaśipu. In the reign of each Manu He kills the demons, fulfills the needs of the demigods and protects all the planetary systems. In the form of Vāmana, the dwarf brāhmaṇa boy, He cheated Bali Mahārāja; in the form of Paraśurāma He rid the earth of kṣatriyas twenty-one times; and in the form of Śrī Rāma He brought the ocean under His submission and killed Rāvaṇa. Descending into the Yadu dynasty, He removed the burden of the earth. In the form of Buddha, by His argumentative preaching in defiance of the Vedas He bewildered the demons who were unqualified to perform sacrifices, and at the end of Kali-yuga He will destroy the śūdra kings in His form of Kalki. In this way the innumerable appearances and activities of the Supreme Personality of Godhead Lord Hari are described.
