No matter what we do wrong, parents will choose to forgive us, because their love for us is the most selfless, and we will always be children in their eyes.
Parents don't ask much of their children, they just want their children to live a happy life, and healthy and lively growth is their greatest wish. Therefore, parents' love for their children is the most selfless and unrequited, just as a bodhisattva is the kindest to her own people and the most generous to all sentient beings.
When children go astray on the road of life, parents will correct them in time, and when children encounter any danger, parents will not hesitate to come forward. Parents really help their children too much, so parents are buddhas and bodhisattvas that we should respect in this life.
The reason why children at home have to be filial to their parents for three years after their parents die is also closely related to their parents being our buddhas and bodhisattvas.
Confucius believes that three years of filial piety does not mean that this is a requirement of normal etiquette, but because it is a respect for parents. Our parents have worked hard to support us all our lives. Even if they didn't fulfill their filial piety when they were alive, we should pray that they will live well on the other side after their parents died.
