It is clear from Geetha that a soul takes rebirth until it attains moksha state.
It is also clear from Geetha that Krishna reincarnates as himself for the establishment of dharma.
Do Krishna's relationships with other souls (when they too are reborn) repeat or vary from one yuga to other?
To put it clearly, let's say soul S lived as wife of Krishna in Dwapara yuga, and S also takes rebirth when Krishna reincarnates, will Krishna take S as his wife or can he take S as his mother, brother, sister, friend etc.?
E.g., Yashoda was the mother of Krishna in last Dwapara yuga. Suppose Krishna and Yashoda take rebirth, then is it always going to be a mother-son relation? Similarly, Subhadra was the sister of Krishna earlier and if they both take rebirth, are they again going to be sister-brother?
My doubt is:
Is there any evidence in our texts that says god can or cannot change his relations with other souls during his incarnations?
