Avatar or Avatara ( , IAST IAST: Avatāra) is often inaccurately translated into English as incarnation. The Sanskrit word IAST2: avatāra literally means "descent" (avatarati) and usually implies a deliberate descent from higher spiritual realms to lower realms of existence for special purposes. Descents that are of importance are mainly that of the Supreme Being which are plenary and marked with superhuman qualities. Other types of descents are limited expansions of Ishvara, and some that are descents of lesser empowered divinities. The term is used primarily in Hinduism for descents of Vishnu whom Vaishnava Hindus (one of the largest branches of Hinduism) worship as the Supreme God, a distinctive feature of Vaishnavism. While Shiva and Ganesha are also described as descending in the form of avatars, with the Ganesha Purana and the Mudgala Purana detailing Ganesha's avatars specifically, the avatars of Vishnu carry a greater theological prominence than those of Shiva or Ganesha and upon examination relevant passages are directly imitative of the Vaishnava avatara lists.Matchett, Freda, Krsna, Lord or Avatara? the relationship between Krsna and Visnu: in the context of the Avatara myth as presented by the Harivamsa, the Visnupurana and the Bhagavatapurana, Routledge, 2000

Avatars of Vishnu

The most traditional form of Avatar within Hinduism is the descents of Vishnu, the preserver or sustainer aspect of God within the Hindu Trinity or Trimurti.

Dasavatara: Ten Avatars of Vishnu in the Garuda Purana

main: Dasavatara of Vishnu

The first four are said to have appeared in the Satya Yuga (the first of the four Yugas or ages in the time cycle described within Hinduism). The next three avatars appeared in the Treta Yuga, the eighth descent in the Dwapara Yuga and the ninth in the Kali Yuga. The tenth is predicted to appear at the end of the Kali Yuga in some 427,000 years time.

1. Matsya, the fish, appeared in the Satya Yuga.
2. Kurma, the tortoise, appeared in the Satya Yuga.
3. Varaha, the boar, appeared in the Satya Yuga.
4. Narasimha, the half-man/half-lion appeared in the Satya Yuga.

8. Krishna (meaning 'dark coloured' or 'all attractive') appeared in the Dwapara Yuga along with his brother Balarama. According to the Bhagavata Purana Balarama is said to have appeared in the Dwapara Yuga (along with Krishna) as a descent of Ananta Shesha. He is also counted as an avatar of Vishnu by the majority of Vaishnava movements and is included as the ninth Dasavatara in some versions of the list which contain no reference to Buddha.
9. Gautama Buddha (meaning 'the enlightened one') appeared in the Kali Yuga (specifically as Siddhartha Gautama).
10. Kalki ("Eternity", or "time", or "The Destroyer of foulness"), who is expected to appear at the end of Kali Yuga, the time period in which we currently exist, which will end in the year 428899 CE.Fact: date=August 2008
