Some idea of the oral sources concerned might be gleaned from the below, reproduced from a relevant newsgroup. The author decided to make it public, so I feel OK about reproducing it here. But I must stress that the author is not me, nor do I share his tradtion.
I use the oghams to build a ninefold chakra system, involving three Goddess forms and six God forms. These chakras form a bridge to the heavenly realms. (cf The rainbow bridge), and provide access to the ninefold law: Survival No Fixed Morals Preservation of Values Loyalty to Elders Maintenance of Community No Compromise Sanctity of Sex Religious Tolerance Expansion of Tradition These together provide a path of manifestation of Sovereignty and provide a ethical technology that enables the individual to explore different aspects of situation and establish their own insights THAT WILL BE IN ACCORD with others in tune with the tradition. That way everyone is entitled to their own truth. Truth against the world. May the Gods grant us affection And in that affection, understanding And in that understanding, reason And in that reason, wisdom And in that wisdom, loyalty And in that loyalty, quickening And in that quickening, affection May we find truth And in that truth, feeling And in that feeling, life And in that life, truth. The truth against the world. Note the six arrtibutes in the first stanza (God), and the three attributes in the second stanza(Goddess), and the final is the others in harmony. Compare with also the enneagram sequences. The nine fold chakras with an implied tenth (Sovereignity -> the nine working in harmony) can also be applied to the Quabbalistic Middle pillar excercise. In addition in the Ogham of the Red Druids there are 13 ogham forms that can be aranged in 78 permutations. cf the Tarot.
