Dashavatars - 10 Avatars of Lord Vishnu
1. Matsya Avatar
2. Kurma Avatar
Tortoise avatar. He supports the cosmos, while the gods and demons churn the cosmic ocean with the help of serpent Vasuki to produce the nectar of immortality (just like churning milk to produce butter). The churning produces both the good and the bad, including poison and immortality nectar. Nobody wants the poison, everyone wants the immortality nectar.
3. Varaha Avatar
Varaha is Boar avatar. He rescues goddess earth when the demon Hiranyaksha kidnaps her and hides her in the depths of cosmic ocean. The boar finds her and kills the demon, and the goddess holds onto the tusk of the boar as he lifts her back to the surface.
4. Narsimha
Narsimha is Half lion-half man avatar. Demon king Hiranyakashipu becomes enormously powerful, gains special powers by which no man or animal could kill him, then bullies and persecutes people who disagree with him, including his own son. The Man-Lion avatar creatively defeats those special powers, kills Hiranyakashipu, and rescues demon's son Prahlada who opposes his own father. The legend is a part of the Hindu festival Holi folklore.
5. Vamana
The 5th avatar of Vishnu, Vamana .Demon king Mahabali fought against the Devas and won heaven, and thus became the ruler of heaven, earth, and the underworlds. Though he was a benevolent king, he was a demon, and the devas led by Indra went to Lord Vishnu to help them get heaven back. Lord Vishnu, although didn't want to punish Bali because he was a good king, instead decided to test him. While the king was distributing alms amongst his people, Vishnu in his Vamana avatar approaches Bali in the form of a monk who offers him food, land, money, jewels, and all the riches. However, the monk refuses and asks only for three steps of land. Bali grants it to him. The dwarf grows, in his first step takes the earth and the netherworld, and in the second all of the heavens. Bali, now understanding who it is in front of him, offers his head to the Lord to put his foot on as the third pace. Lord Vishnu gave him the boon of immortality and allowed him to return to his people every year on the occasion of Onam.
6. Parashurama
Sage with an axe avatar. The warrior class gets too powerful, and seizes other people's property for their own pleasure. The avatar appears as a sage with an axe, kills all the adharmi kings and all his warrior companions.
7. Rama
Lord Rama is one of the most significant and powerful deities of Hindu dharma and the lead character of the epic Ramayana. He kills the evil king Ravana to end his terrorizing rule, and to free his wife Sita, whom Ravana had kidnapped.
8. Krishna
Lord Krishna is yet another major form of Lord Vishnu. He is known to end the reign of his tyrannical maternal uncle Kansa, and for his role as the advisor or the Pandavas and the charioteer and guide of Arjuna in Mahabharata.
9. Balarama
Balarama (Sanskrit: बलराम, IAST: Balarāma) is a Hindu god and the elder brother of Krishna. He is particularly significant in the Jagannath tradition, as one of the triad deities. He is also known as Baladeva, Balabhadra, Haladhara and Halayudha. The first two epithets refer to his strength, the last two associate him with Hala (Langala, "plough"] from his strong associations with farming and farmers, as the deity who used farm equipment as weapons when needed .Balarama is sometimes described as an avatar of Shesha, the serpent associated with the god Vishnu; Krishna is regarded as an avatar of Vishnu. Some traditions regard him as one of 10 principle avatars of Vishnu himself.
Balarama's significance in the Indian culture has ancient roots. His image in artwork is dated to around the start of the common era, and in coins dated to the 2nd-century BCE.[6]In Jainism, he is known as Baladeva and has been a historically significant farmer-related deity.
Kalki is the only avatar of Vishnu that is yet to be born. It is said that he will end all evil by defeating the demon Kali and start a new Satyayuga or Kalkiyuga. Kali is all the negative emotions and elements personified into one. Kalki is depicted as a warrior riding a white horse and holding a shining sword.
