9th Harmonic chart?

1
I've never heard of this before tonight and now I'm very interested. What exactly does it do? I read the metaphor 'The birth chart is the roots and the 9th harmonic is the fruit'. I'm interested because in my 9th harmonic chart Saturn is in its domicile (Capricorn), Mercury is in domicile (Virgo) and Venus and Mars are in mutual reception (Libra and Aries). But I'm confused because my 9th harmonic ascendant is Taurus but it's saying my MC is in the 5th house in Virgo..So I don't know how to interpret where the other planets would be. Anyways, anybody have any history or knowledge of this?
