Likutei Moharan 69:5/ליקוטי מוהר"ן ס״ט:ה׳

15. This is also the concept of the estate rights, which belong to the children. When fruits appear, they sometimes still have need of their branches, to draw sustenance from them. Therefore, when [their father] passes away and they can no longer draw sustenance because the nourishing of the tree has ceased, [the children] receive and inherit the money due them, in order to complete their light. And [their mother] receives the balance due her for her light; this being the concept of her taking the marriage contract.

2At other times, the children take the inheritance even though they have no need for any additional light from the branches. This is for a different reason. When the children come into the world, at that moment their spouses, money and children—i.e., the tree, branches and fruits—come into the world with them, and their father gathers up their light. Thus it is possible that the father may also have money on his children’s account, through his gathering up the parts of their light. Therefore, they occasionally take the inheritance even though they have no need of their mother, of receiving light from her branches. They nevertheless take their money, which their father gathered up through them, from the parts of their lights.

3In truth, the inheritance should not be divided equally, since the parts of their lights are certainly not equal. However, it is impossible to hand over this judicial decision to the courts of this lower world. For only the Knower of Mysteries knows how to make these distinctions. And in truth, He later arranges things as they ought to be, taking from one and giving to the other.
