Past Parents

I asked him why he doesn’t seem very concerned for the spiritual well-being of his parents. He replied that since we have been reborn so many times, we have all been one another’s parents at some point in the past, and that if so, he doesn’t see why he should be too particular about his present set of parents. It seems vaguely logical at first… but upon closer scrutiny, he isn’t very unconditionally and equanimously helpful to other beings either.

And if one is not even very concerned about one’s present parents, who are the most clear and present parents now, can one truly care more about strangers, other ‘past parents’? Spiritual charity begins at home, unless there are obstacles at the moment, which we should strive to overcome too. Right?
