4 Planets with Nodes !

Hi Ernst,

Does it have to be four planets in conjunction with the nodes always to have those tendencies or generally Sun, Moon, Me, Saturn Avasthas have a say how the person's psyche play out to atleast some extent! For example, can we say if Sun and Moon not in great Avasthas but not with nodes, still person will have difficulties to navigate through life since Parent and Child sort of afflicted?! also, is it only Avasthas matters in this regard or Shadbala also will be a factor as in how much person going to have effect on?

Sincerely
