Either you are Aryan or Kiratis.
This history of Nepal evolve through these two Races coming to Indian-SubContinent
in pre-historic times.
In Nepal, Kiratis are the Indigenous people having settle along the Himalayas regions first.
The Aryans later having coming from India meets the Kiratis and the two civilizations plays
an important role's in shaping history and culture of India, in which Nepal becomes the center of these two civilizations.
The Kiratas in Vedic Literature.
The name Kirata is for the first time found in the Yajurveda (Sukla Yajurveda, Vajasaneya, XXX, 16;
also Krsna Yajurveda, Taittiriya Brahmana, III, 4,12,1).
In connexion with the Purusa-medha or 'Man-Offering' sacrifice, where a list of all kinds of human beings and animals symbolically or figuratively offered to the gods as sacrifice is given, we find the following passage:--
guhabhyah Kiratam; sanubhyo Jambhakam; paravatebhyah Kimpurusam
which upon translation will read 'A Kirata, for the caves; a Jambhaka (long-toothed man?) for the slopes;
a Kimpurusa (an ugly man, a wild man, an ape?) for the mountains.'
Then in the Atharvaveda (X,4,14) we have a reference to a Kirata girl (Kairatika) who digs a herbal remedy on the ridges of the mountains:--
Kairatika kumarika saka khanati bhesajam:
hiranyayibhir abhribhir girinam upa sanusu.
'The young maid of Kirata race, a little damsel, digs the drug:
Digs it with shovels wrought of gold on the high ridges of the hills.'
(Translation by R.T.Griffith.)
"Macdonell and Keith have the following note in their Vedic Index on Kirata:
'Kirata is a name applied to a people living in the caves of the mountains, as appears clearly from the dedication of the Kirata to the caves in Vajasaneyi Samhita (also Taittiriya Brahmana), and from the reference to a Kirata girl, who digs a remedy on the ridges of the mountains.
The Manava Dharma-sastra regards the Kiratis as degraded Ksatriyas (ref. X, 44).'
When a non-Aryan or foreign people is describes in an old Indian text as being of degraded Kshatriya origin,
there is always an implication that they were, to some extend at least, advanced in civilisation or military organisation". -- Suniti Kumar Chatterji (KIRATA-JANA-KRTI)
"The allusions to the separate family of the Kiratas (Kirata Kula) in some of the Brahmanas also
indicate that they were the original inhabitants of India. Relying on
the information supplied in the Vedic Samhitas and Brahmanas herein
referred to it has been correctly stated that the name Kirata was
applied to the aboriginal hill folk. They were the class of people, who
inhabited the woods and the caves of the mountains
and supported themselves by hunting. They were barbarous non-Aryan
tribes representing the degraded race." --G.P Singh (The Kiratas in
Ancient India)
