King Citraketu Meets the Lord

yathā —just as;  vastūni —commodities;  paṇyāni —meant for trading;  hema-ādīni —such as gold;  tataḥ tataḥ —from here to there;  parya-tanti —move about;  nareṣu —among men;  evam —in this way;  jīvaḥ —the living entity;  yoniṣu —in different species of life;  kartṛṣu —in different material fathers.
TRANSLATION
Just as gold and other commodities are continually transferred from one place to another in due course of purchase and sale, so the living entity, as a result of his fruitive activities, wanders throughout the entire universe, being injected into various bodies in different species of life by one kind of father after another.
PURPORT
It has already been explained that Citraketu’s son was his enemy in a past life and had now appeared as his son just to give him more severe pain. Indeed, the untimely death of the son caused severe lamentation for the father. One may put forward the argument, “If the King’s son was his enemy, how could the King have so much affection for him?” In answer, the example is given that when someone’s wealth falls into the hands of his enemy, the money becomes the enemy’s friend. Then the enemy can use it for his own purposes. Indeed, he can even use it to harm its previous owner. Therefore the money belongs neither to the one party nor to the other. The money is always money, but in different situations it can be used as an enemy or a friend.
As explained in  Bhagavad-gītā , it is not by any father or mother that the living entity is given his birth. The living entity is a completely separate identity from the so-called father and mother. By the laws of nature, the living entity is forced to enter the semen of a father and be injected into the womb of the mother. He is not in control of selecting what kind of father he will accept.  Prakṛteḥ kriyamāṇāni : the laws of nature force him to go to different fathers and mothers, just like a consumer commodity that is purchased and sold. Therefore the so-called relationship of father and son is an arrangement of  prakṛti , or nature. It has no meaning, and therefore it is called illusion.
