It is obvious that the British carried this conception of the innate divinity of man much farther than merely to the personalities of kings. The word _soul_, Dutch _ziel_, is probably the French word _ciel_; to work with _zeal_ is to throw one's _soul_ into it. That the Celts, like the Chinese or Celestials, equated the _soul_ with the _ciel_ or the Celestial, believing, as expressed by Taliesin, the famous British Bard, that "my original country is the region of the summer stars," is unquestionable. Max Müller supposed that the word _soul_ was derived from the Greek root _seio_, to shake. "It meant," he says, "the storm-tossed waters in contradistinction to stagnant or running water. The soul being called _saivala_ (Gothic), we see that it was originally conceived by the Teutonic nations as a sea within, heaving up and down with every breath and reflecting heaven and earth on the mirror of the deep." Whatever the Teutonic nations may have fancied about their souls is irrelevant to the Druidic teaching, which was something quite different. In A.D. 45, a Roman author stated that the Druids (who did not flourish in Germany) taught many things privately, but that _one_ of their precepts had become public, to wit, that man should act bravely in war, that souls are immortal, and that there is another life after death. There is additional testimony to the effect that the Druids of the Isle of Man, or Eubonia, "raised their minds to the most sublime inquiries, and despising human and worldly affairs strongly pressed upon their disciples the immortality of the soul". "Before all things," confirmed Cæsar, "they (the Druids) are desirous to inspire a belief that men's souls do not perish." That they successfully inspired this cardinal doctrine is proved by the fact that among the Celts it was not uncommon to lend money on the understanding that it should be repaid in the next world. It is further recorded that the Britons had such an utter disregard of death that they sang cheerily when marching into battle, and in the words of an astonished Roman, _Mortem pro joco habent_--"They turn death into a joke".
