The primordial tradition of the present Manvantara
As we have indicated elsewhere, this symbolism, of clearly Hyperborean origin, is one of the marks of the direct connection of the Celtic tradition to the primordial tradition of the present Manvantara, whatever other elements from earlier but already secondary and derivative traditions may have come to be added to this main current and as it were reabsorbed into it. What we mean here is that the Celtic tradition could in all probility be regarded as one of the ‘points of junction’ between the Atlantean tradition and the Hyperborean tradition, after the end of the secondary period during which the Atlantean tradition represented the predominant form and, as it were, the ‘substitute’ for the original centre which was already accessible to common humanity.
