Hey Simone
I will give you all the info I have on the subject. I was told about the nodes many yrs ago but I remember this:

I was told that my South Node in Aries 2nd house tells of past lives of not caring about relationships as much as myself and my own posessions....
Now I have a stelenium of planets in the 7th, 8th, 9th and 10th (North Node in Libra in the 8th - thats alot of forced karma to face) - that means in this life I am "forced" to take other people into consideration and I "need" other people

I imagine:
your south node in the 9th relates to having strong emotional ties to religious and philosophical beliefs. As the Moon rules Cancer, the emotional impulses of the Moon were felt in affairs of publicity and promotion, and personal recognition for you. You worked in a selfless fashion, with as sense of emotional vigor, for causes in which you believed. You probably traveled and experienced alot of different types of cutures....You were probably more emotional/passionate than cautious about what you said and did with things related to the ninth house. You came into this life already having that ability "under your belt" so to speak.

In this life, you are propelled to grow toward the Capricorn influence in the third house
You need to work on being careful with your expression of thoughts and ideas. You should refrain from writing or saying anything unless there is a reason for doing so. you may feel you are being secretive when you do this because your instinct is to let it all out (emotionally).
In this life, chose your words carefully for maximum effect. Sometimes this results in harsh and exacting speech. In your later life, you may want to continiue studying to abtain your ambitions...

Thats my educated "guess" :-)

Heres a bit more...

The Dragon's Head (North Node):
The Dragon's Head represents your karmic objectives in this lifetime. It points the way towards soul growth and evolution. The sign holding your Dragon's Head reveals the flavour of your karma in this lifetime, while its house placement shows the area of life in which you need to develop, or become conscious of this karma. Aspects to the North Node concern or affect relationships to prevailing trends, attitudes and opportunities. Some modern astrologers hold that we should try to "actualise" the North Node at the expense of the South Node (!), but in reality the two nodes are like two sides of the same coin, just like the yin and yang of the Tao. The Dragon's Head does mark sets of circumstances that are in some way new or unfamiliar, an exploratory course that leads to the realisation of the desires and past-life commitments expressed by the placement of the Dragon's Tail.
Positive aspects to the Dragon's Head are generally favourable from the benefics (Venus and Jupiter), Sun, Moon and Mercury, whilst sextile or trine from Mars, Uranus, Saturn, Neptune and Pluto also have beneficial effects. Square and opposition from the benefics and conjunction, square and opposition from the malefics (Mars and Saturn; Uranus) are unfortunate, according to the matters signified by the house and planet concerned.


The Dragon's Tail (South Node):
Past life hangovers are represented by the position and aspects of the Dragon's Tail. This in a sense is a "comfort zone" but the growth patterns expressed through the Dragon's Head find their origins in a longing, or an urge for fulfilment in areas marked by the South Node's position in the chart. This is a very important position and often provides great insight into the urges that drive our lives.
Aspects to the Dragon's Tail display the results of innate unconscious tendencies and karmic patterns as they emerge in life. They tend to be separative and destructive. Any aspect to the South Node from any planet is unfortunate for matters to do with the house and planet activated thereby.
The position of the Dragon's Tail is generally indicative of past life connections or commitments in a relationship analysis. Relationships that seem somehow fated or inevitable usually have a strong South Node connection. Aspects thereto are also most interesting (especially if a pre-natal eclipse falls there), whether natally or in conjunction with a progression or major transit.

The best way to understand the astrological nature of the Nodes might be to envisage them as bubbling pools of karmic energy. These have a massive potency, which is associated with powerful events and feelings whenever they are activated by progressions or transits. Because the nodes are pools of karma associated primarily with the house in which they are located, the related effects are deep and often seem almost inevitable. It is not for nothing that they are called the Dragon's Head and Tail...

hope i helped!

Mars in Gemini: An angy writer, journalist or lecturer, a salesman , infedile man, one who caused conflict due to his restless temperament, a liar unaware of this trait.

Maybe in this life I am paying back for the conflict I have caused in the past life.
