Suppose you have four laya centers in Europe: four Foci through which psychic impulses from the Oversoul pour through into this world. A Mediterranean point, perhaps in Italy; a Teutonic point in Sweden; a Celtic point in Wales-Ireland (formerly a single island, before England rose out of the sea); and a Slavic point, probably in Russia. The moment comes for such and such a 'race' to expand; the Mediterranean, for example. The Italian laya center, Rome, quickens into life. Rome conquers Italy, Gaul, Spain, Britain, the East; becomes _Caput Mundi._ Countries that shortly before were Celtic in blood, become, through no material change in that blood, Latin; by language, and, as we say, by race. The moment comes for a Teutonic expansion. The laya center in Sweden quickens; there is a Swedish or Gothic invasion of Celtic lands south of the Baltic; the continental Teutons presently are freed. It is the expansion of a spirit, of a psychic something. People that were before Celts (just as Mr. Dooley is an Anglo-Saxon) become somehow Teutons. The language expands, and carries a tradition with it. Head measurements show that neither Southern Germany nor England differs very much towards Teutonicism from the Mediterranean type; yet the one is thoroughly Teutonic, the other Anglo-Saxon. Sometimes the blood may be changed materially; often, I suppose, it is changed to some extent; but the main change takes place in the language and tradition; sometimes in tradition alone. There was a minor Celtic quickening in the twelfth century A. D.; then Wales was in a fervor of national life. She had not the resources, or perhaps the will, for outside conquest. But her Authurian legend went forth, and drove Beowulf and Child Horn out of the memory of the English, Charlemagne out of the memory of the French; invaded Germany, Italy, even Spain: absolutely installed Welsh King Arthur as the national hero of the people his people were fighting; and infused chivalry with a certain uplift and mysticism through-out western Europe. Or again, in the Cinquecento and earlier, the Italian center quickened; and learning and culture flowed up from Italy through France and England; and these countries, with Spain, become the leaders in power and civilization.
