It is a known fact in Human migration that wherever there is a natural calamity in the form of a Tsunami, people of Asia migrated towarda the west;one heading through the Middle east and another through the Caucasus.
A group led by Shiva with Ganesha left through the Middle east route and Satyavrata Manu’s Group went to Ayodhya to found Ikshvaku Dynasty, ord Rama’s Dynasty.
That is the reason we find more of Shiva and Ganesha relics in the Mesopotamian area of Iraq,Kuwait,South America and Africa and more of Krishna relics in Iran, Russia.
Shiva seems to find a place everywhere.
One of the reasons is that Shiva must have returned to Sarasvati Valley from the Arctic after the compilation of Rig Veda.
Though there are indications that the people of England, Celts did have a Sanatana Dharma connection, I have not been able to find a good research work till now on this subject.
Now,
There is enough evidence that the priestly class of the ancestors,Druids, of the Celts were…. Brahmins.
And they performed the Vedic rituals.
“The Druids of the ancient Celtic world have a startling kinship with the brahmins of the Hindu religion and were, indeed, a parallel development from their common Indo-European cultural root which began to branch out probably five thousand years ago. It has been only in recent decades that Celtic scholars have begun to reveal the full extent of the parallels and cognates between ancient Celtic society and Vedic culture.
The Celts were the first civilization north of the European Alps to emerge into recorded history. At the time of their greatest expansion, in the 3rd century bce, the Celts stretched from Ireland in the west, through to the central plain of Turkey in the east; north from Belgium, down to Cadiz in southern Spain and across the Alps into the Po Valley of Italy. They even impinged on areas of Poland and the Ukraine and, if the amazing recent discoveries of mummies in China’s province of Xinjiang are linked with the Tocharian texts, they even moved as far east as the area north of Tibet.
The once great Celtic civilization is today represented only by the modern Irish, Manx and Scots, and the Welsh, Cornish and Bretons. Today on the northwest fringes of Europe cling the survivors of centuries of attempted conquest and “ethnic cleansing” by Rome and its imperial descendants. But of the sixteen million people who make up those populations, only 2.5 million now speak a Celtic language as their mother tongue.
The Druids were not simply priesthood. They were the intellectual caste of ancient Celtic society, incorporating all the professions: judges, lawyers, medical doctors, ambassadors, historians and so forth, just as does the brahmin caste. In fact, other names designate the specific role of the “priests.” Only Roman and later Christian propaganda turned them into “shamans,” “wizards” and “magicians.” The scholars of the Greek Alexandrian school clearly described them as a parallel caste to the brahmins of Vedic society.
The very name Druid is composed of two Celtic word roots which have parallels in Sanskrit. Indeed, the root vid for knowledge, which also emerges in the Sanskrit word Veda, demonstrates the similarity. The Celtic root dru which means “immersion” also appears in Sanskrit. So a Druid was one “immersed in knowledge.”
Because Ireland was one of the few areas of the Celtic world that was not conquered by Rome and therefore not influenced by Latin culture until the time of its Christianization in the 5th century ce, its ancient Irish culture has retained the most clear and startling parallels to Hindu society.
Professor Calvert Watkins of Harvard, one of the leading linguistic experts in his field, has pointed out that of all the Celtic linguistic remains, Old Irish represents an extraordinarily archaic and conservative tradition within the Indo-European family. Its
nominal and verbal systems are a far truer reflection of the hypothesized parent tongue, from which all Indo-European languages developed, than are Classical Greek or Latin. The structure of Old Irish, says Professor Watkins, can be compared only with that of
Vedic Sanskrit or Hittite of the Old Kingdom.
The vocabulary is amazingly similar. The following are just a few examples:
Old Irish – arya (freeman),Sanskrit – aire (noble)
Old Irish – naib (good), Sanskrit – noeib (holy)
Old Irish – badhira (deaf), Sanskrit – bodhar (deaf)
Old Irish – names (respect), Sanskrit – nemed (respect)
Old Irish – righ (king), Sanskrit – raja (king)
This applies not only in the field of linguistics but in law and social custom, in mythology, in folk custom and in traditional musical form. The ancient Irish law system, the Laws of the Fénechus, is closely parallel to the Laws of Manu. Many surviving Irish myths, and some Welsh ones, show remarkable resemblances to the themes, stories and even names in the sagas of the Indian Vedas.
Comparisons are almost endless. Among the ancient Celts, Danu was regarded as the “Mother Goddess.” The Irish Gods and Goddesses were the Tuatha De Danaan (“Children of Danu”). Danu was the “divine waters” falling from heaven and nurturing Bíle, the sacred oak from whose acorns their children sprang. Moreover, the waters of Danu went on to create the great Celtic sacred river–Danuvius, today called the Danube. Many European rivers bear the name of Danu–the Rhône (ro- Dhanu, “Great Danu”) and several rivers called Don. Rivers were sacred in the Celtic world, and places where votive offerings were deposited and burials often conducted. The Thames, which flows through London, still bears its Celtic name, from Tamesis, the dark river, which is the same name as Tamesa, a tributary of the Ganges.
Not only is the story of Danu and the Danube a parallel to that of Ganga and the Ganges but a Hindu Danu appears in the Vedic story “The Churning of the Oceans,” a story with parallels in Irish and Welsh mytholgy. Danu in Sanskrit also means “divine waters” and “moisture.”
In ancient Ireland, as in ancient Hindu society, there was a class of poets who acted as charioteers to the warriors They were also their intimates and friends. In Irish sagas these charioteers extolled the prowess of the warriors. The Sanskrit Satapatha Brahmana says that on the evening of the first day of the horse sacrifice (and horse sacrifice was known in ancient Irish kingship rituals, recorded as late as the 12th century) the poets had to chant a praise poem in honor of the king or his warriors, usually extolling their genealogy
and deeds.
Such praise poems are found in the Rig Veda and are called narasamsi. The earliest surviving poems in old Irish are also praise poems, called fursundud, which trace back the genealogy of the kings of Ireland to Golamh or Mile Easpain, whose sons landed in Ireland at the end of the second millennium bce. When Amairgen, Golamh’s son, who later traditions hail as the “first Druid,” set foot in Ireland, he cried out an extraordinary incantation that could have come from the Bhagavad Gita, subsuming all things into his being [see sidebar right].
Celtic cosmology is a parallel to Vedic cosmology. Ancient Celtic astrologers used a similar system based on twenty-seven lunar mansions, called nakshatras in Vedic Sanskrit. Like the Hindu Soma, King Ailill of Connacht, Ireland, had a circular palace constructed with twenty-seven windows through which he could gaze on his twenty-seven “star wives.”
There survives the famous first century bce Celtic calendar (the Coligny Calendar) which, as soon as it was first discovered in 1897, was seen to have parallels to Vedic calendrical computations. In the most recent study of it, Dr. Garret Olmsted, an astronomer as well as Celtic scholar, points out the startling fact that while the surviving calendar was manufactured in the first century bce, astronomical calculus shows that it must have been computed in 1100 bce.
One fascinating parallel is that the ancient Irish and Hindus used the name Budh for the planet Mercury. The stem budh appears in all the Celtic languages, as it does in Sanskrit, as meaning “all victorious,” “gift of teaching,” “accomplished,” “enlightened,” “exalted” and so on. The names of the famous Celtic queen Boudicca, of ancient Britain (1st century ce), and of Jim Bowie (1796-1836), of the Texas Alamo fame, contain the same root. Buddha is the past participle of the same Sanskrit word–“one who is enlightened.”
For Celtic scholars, the world of the Druids of reality is far more revealing and exciting, and showing of the amazingly close bond with its sister Vedic culture, than the inventions of those who have now taken on the mantle of modern “Druids,” even when done so with great sincerity.’
