The principle fostering a healthy birth is the same that underlies healthy child development: parents must embrace their limits and very death in order for the child to have life and to flourish. In other words, the death of the parent begets the life of the child.
The question isn’t if we have a devouring parent, because all humans have a natural bent to devour. The question is how we respond to our parents. Many people want to forgive their parents, which is a good inclination. But what does real forgiveness entail? What it doesn’t entail is enabling the parent to continue devouring.
Our healthy differentiation from our parents leads to our life, and quite possibly their reincarnation, in this lifetime.
