Chasidut for Bava Batra 316:7
שלחו מתם בן שלוה בנכסי אביו בחיי אביו ומת בנו מוציא מיד הלקוחות וזו היא שקשה בדיני ממונות לוה מאי מפיק ועוד לקוחות מאי עבידתיה אלא אי איתמר הכי

Kedushat Levi
Since the generation who left Egypt as adults did not get to the land of Israel, only their sons, it follows that the parents did not achieve their שלימות, “maturity” until their sons had made the Land of Israel their ancestral heritage. This is the meaning of “the dead inherited the living.”
This statement in the Talmud about the dead inheriting the living, also explains another statement in the Talmud Sanhedrin 104, according to which a son [while alive Ed.] can confer spiritual merits on his [deceased] father, whereas his deceased father cannot confer merits on his surviving son. The Talmud bases this on the example of the second generation of the Israelites bestowing merits on their fathers after they carried out the task set by G’d for this people of settling in the Holy land and observing the Torah there. Avraham after his death, or Yitzchok, after his death, could not confer merits on their respective sons that these had not acquired during their respective lifetimes.
