Didn't you say there was a causal cycle? Then what do you think was the relationship between our parents and us in their previous lives?

Parents in a previous life are not necessarily parents in this life;

Parents in this life may not be parents in the next life;

Since the infinite robbery, the immortal parents are all beings in the world today. They may be passers-by, teachers or friends. C. For ordinary people who can't remember past lives, there is no way to know.

So the Buddha taught us to cherish all sentient beings equally, that is, to cherish our parents from generation to generation.
