Hi. I decided to register just so I could respond to your question. I hope it isn't so old you miss it because this is an important question. In my experience, the nodal opposition is sort of like a pole reversal.
The north node is magnetic, yin, like the north pole, and resides at the top of the head in the body. It is also like the intersection in mathematics. The glyph is even the same. The intersection shows what you have in common with others and what is different. If you were to draw two circles partially overlapping, the intersected area, which looks like a yoni, represents what you have in common and the other two areas represents what you don't have in common. Those two areas look like the waxing and waning Moon. You could also look at this symbol as the two coming together as separate individuals with the union shown where they overlap or join. While one rises in energy the other wanes. In a sexual union each would take their turn in reaching the summit.
The south node is perhaps electric, but probably best described as repulsive, yang, like the south pole. In the body it resides at the base of the perineum. Energy is drawn in through the crown and grounds us to earth. In mathematics the symbol corresponds to the Union. Here both circles are completely overlapped, sharing everything in common. This would be like a complete merging with another in sacred sex, reaching the summit together, intensifying the power.
When the transiting north node passes over the natal south node it teaches us how the serpent bites his own tail. During the last trimester of gestation the baby moves to the head down position and stays there in preparation for birth. During this time his north node is aligned with the mother's south pole. This is a pole reversal between too beings. During this time the greatest growth occurs. All of the body fat necessary to maintain his body temperature is acquired (adding about a pound per week in those last weeks) and all of the vital organs complete there maturing process, the lungs and liver being the most crucial notable changes.
I've heard and read that many believe the earth has gone through many pole reversals and at that the effect is like placing a tape near a magnet. The memory gets erased. This is how they explain the evolved knowledge that has disappeared, having to be regained. Perhaps, during fetal development this is when the memory of past lives disappears. It is also possible that when they reverse every 18 years or so, that this is a time we regain memory of skills or knowledge previously developed. It is also a time that thrusts you onto the right path if you've strayed, perhaps taking away previous desires.
I also read somewhere that the ideal planetary configuration has the nodes on the outside perimeter of the planets, thus containing them. I have a bowl chart with the nodes the outer rim so perhaps it is easier for me to see the effect of the reversals.
At my first opposition, I was thrust into puberty, being the only girl in the whole elementary school that NEEDED a bra.
My south node is in Cancer, the sign of the breasts in the house of peers, the 11th. This was probably the first time I really felt like I was different than average or the norm. The north node drew energy into my south node and expanded them. The south node met my north node in the 5th, schools attended. Shortly after this my mom lost her job and we lost our home. Later she lost her children as her mother reported it and the courts took us away.
My second opposition occurred when I inherited supplies for oil painting when my husband's grandma died. I quickly picked up the skills producing quite nice paintings in a very short time, leading me to believe that this is a skill I already had developed and was "re-membering", thus, my belief that the north node on the south node can draw in past memory. I also sense that, while bringing in distant memory, more recent memory may be erased somewhat, actually, just moved from the conscious to the unconscious storage area. The purpose of this may be to shift our focus to the future rather than holding on to the past.
My last opposition (yes, exposing my age
) occurred while I was carrying my 7th son. It was the transition from 1st to 2nd trimester. I clearly did not intend to have another child but the universe had other plans for me. This time sent me in the right direction. What is interesting is that he is more his dad’s child than mine. South node is in 11th which is the 5th of the 7th. All my other children were mine, more than their dad’s. I did everything for them other than bring home the paycheck for their food. This child, while only I could feed him at breast, is so much like his dad, right down all the cusp degrees. He is very attached to him and his dad does as much of the nurturing as I do. I suppose it could just be because this is a different husband, my other sons were with my first husband, but I don’t think that is all there is too it. He is so different. And he doesn’t have the normal attachment to mom that one would expect especially with his Cancer Sun. This must have accelerated his growth also since he decided to break out of his watery home 5 weeks early, probably due to an unbelievable amount of stress I was under in the workplace. I was getting comments about big breasts then too. Since that time I have been thrust, not only out of that job, but out of that field all together since some nerve problems are limiting the amount of forceful physical labor I can now do.
Hope this helps,
Connie
