Ikar toldos of tzadikim? Arent everyone's deeds their main produce?
Most people change focus from their own growth to their children's. So their ikar toldos are the children. A tzaddik continues to work on himself so that even aftwr raising children his ikkar toldos are his own massim tovim.
I just saw anaf yosef on tanchumah noach 3 that brings on this passuk, whoever does torah truthfully is like he creates himself.
