I read answers about Krishna and Rama as source of all avatars on this site. Are there any verses that support Vishnu as source of all avatars? Since there are different Vishnus and such complexity in pancharatra, I want to know about root Vishnu from whom all other Vishnus and avatars emanate. Which Vishnu is talked about when we say Vishnu's 10 avatars. Please quote Sanskrit verse and translation.
The Lord Visnu took the incarnations of Matsya (fish), Kurma (tortoise), Varaha (boar) Nfhari (Man-lion), Vamana (Dwarf) the powerful ParaSurama, Rama son of Dalaratha Krsna, Buddha and Kalki for the destruction of demons and ogres. In the same way the manifest and unmani- fest form of the primordial Gadadhara. GP 1.86.10-11
Yes. There is.
In Ananda-Ramayana (Saara-Kanda Sarga 3), we get:
अष्टावंशेन विधृता अवताराश्च विष्णुना। रामकृष्णावतारौ च पूर्णरूपेण तौ धृतौ॥
meaning: Avarataaras are born out of one- eighth parts'Kalaas' of Vishnu, Rama and Krishna beingnPurna-Avataaras.(quoted in Pranava-Preama-Pijusha Bhashya of Srimad-Bhagavad-Gita, Sitaramdas Omkarnath, Mahamilan Math, vol.2, page 48)
Sri Shankaracharya writes in His Vishnushatpadi (Ref:Stavakusumanjali, Swami Gambhirananda(Edited) Udbodhan, page 246:)
O lord Vishnu, You protect this world by assuming different forms of Avataaras as Matsa, Kurma etc: "Matsyadibhi ravatarair avataa avata yada vasudhaam.
Regarding 'which Vishnu is being referred to, we have to know the meaning of the word 'Vishnu'.
"vebeshti vyaapnoti vishwam yah sa vishnuh" meaning He who is all-pervading >is Vishnu.Alternatively, "veshati sinchati aapyaayante vishwam iti va" meaning Who entertains or enters into ALL beings is Vishnu. >Thirdly,"vishnaati vijunakti bhaktaan mayaapasarena samsaaraadid iti ba" >meaning Who removes the maya and uplifts devotees from the worldliness is >Vishnu. Fourthly, "yasmaad vishwam idam sarvam tasya shaktyaa samudbhavah/ >tasmaadevochchyate vishnur vishadhaatoh praveshanaat" meaning He Whose Power >has created the entire universe, or who is in everything is Vishnu".So Vishnu is the name of the Supreme Godhead.(Ibid, vol 1, page 295)
This is from Mahabharata, Adi parva, 1.57, which states that Krishna is an incarnation of Vishnu -

Translation by van Buitenen - Visnu, whose fame is great, who is worshiped by all the worlds, the Unmanifest, Aksara, Brahman, and Cause, to favor all the worlds became manifest in Devaki by Vasudeva–God without beginning or end, the Lord Maker of the universe, who is without attributes as well as the imperishable Soul, and Nature, the ultimate Source, the Man, the Maker of all things, the Yoker of Being, the stable Intransient, the Unending, Unmoving God, the Swan, the Lord Nārāyana, whom they call the unaging, sempiternal Place, supreme and everlasting. He is the ubiquitous Man, Maker, and Grandfather of all creatures; and so in order to further the growth of the Law, he was born amidst the Andhaka-Vršnis.
