"in some way beneficently aspecting the NN"

In astrology, "beneficent" means 'kind' or 'friendly' aspects. I was indicating trines and sextiles. "Maleficent" means hard, i.e. squares, inconjuncts, oppositions.

"more motivating force to embody that point in a native's chart"

Mars=motivating force. Embodying one's North Node means to engage with what we are drawn toward. If I have a Virgo NN (which I do) I am embodying Virgo energy when I am in healer mode, or in some sort of service to someone, just as two examples.

"Squares, inconjuncts (quincunxes) and oppositions ( guess the latter is more obvious cuz it's then on the SN) between Mars and NN pull one away from embodying that point/style/energy."

the latter=opposition. If Mars is opposing the North Node, it is conjunct the South Node. If I had Mars square or quincunx my North Node, I would not as easily be able to embody (engage with) the energy of that point.

"Whatever Mars touches, it catalyzes and activates. "

Mars "touching" a planet means it aspects that planet.

It would have felt kinder to me if you'd simply asked me to explain.

P.

think about when Saturn was placed, when you were at 6.

I am Libra When Saturn lied in Libra, I got stitches on my face.
when Saturn in Pisces(7-8th in my chart), I went through death, birth, marriage around me.

There are many elements that cause the accidents in life- see, Michael Jackson, Princess Diana...

Tracking down the Saturn order in your past is the first thing we can do to briefly understand major happenings.
