Dear Uner,
the second example is under sade sati right now in first phase. The best way to understand Sade satio is to realize that it is Sani who is making us to change. He-sani epresents vayu tatva and it is all about changing. If we are able to change, to take everything as it comes it is good for us. We are all seeking the change but when it comes many people doesnt really want that change and it hurst. This is more during sade sati. So go with a wind and it will be much easier. During sade sati many good things can happen as marriage, or traveling, stay to foreigh countries, but anyway it is a feeling as when u stay alone you feel emptiness - it is Chanda, manas it is transiting. Also it is said that during first sadhe sati our grandparents can leave (Sani is vayu, separation, pain and sorrow), during second cycle our parents etc.
We should also look at Sade sati in NAvamsa cart as it represents good or bad luck we brought from previous birth regarding some specific graha (we know that neecha graha in rasi gets neecha banga if it is ucha in navamsa). So that Sade sati can be even harder for a native.
If I am getting good cart there is Surya in first degree, hence Surja sankranti dosa is obvious. If it is not please infor me. How is partnership?
Best wishes, Bojan
