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.
