the matsya purana gives the list of ten avatars of which three are divine avatars
Dashavatara The list of Dashavatara varies across sects and regions. The standard list is as follows: Matsya, Kurma, Varaha, Narasimha, Vamana, Parashurama, Rama, Krishna, Buddha, and Kalki. Sometimes, Krishna replaces Vishnu as the source of all avatars and Balarama takes Krishna's place in the list. In other versions, Krishna may be dropped from the list and substituted by regional deities like Vithoba, Jagannath or Balarama.
Upanishads More than 200 Upanishads are known, of which the first dozen or so are the oldest and most important and are referred to as the principal or main (mukhya) Upanishads.[14][15] The mukhya Upanishads are found mostly in the concluding part of the Brahmanas and Aranyakas[16] and were, for centuries, memorized by each generation and passed down orally. The early Upanishads all predate the Common Era, five[note 6] of them in all likelihood pre-Buddhist (6th century BCE),[17] down to the Maurya period.[18] Of the remainder, 95 Upanishads are part of the Muktika canon, composed from about the last centuries of 1st-millennium BCE through about 15th-century CE.[19][20] New Upanishads, beyond the 108 in the Muktika canon, continued to be composed through the early modern and modern era,[21] though often dealing with subjects which are unconnected to the Vedas.[22]
