There are three types of family in life.
One is purely biological and you know it since birth. It renews itself and expands during life, because some relatives die and others are born, while other relatives cross with other families. This family is usually the only family most people know. You can feel in tune with this family or not, having a strong or weak bond with them.
There is also another family, which exist before birth and after death, dwelling beyond the linearity of time. It is a shadow family, which always follows you during life, whether you accept it or not. It is not based on blood or kinship ties. It is based on very subtle and powerful bonds.
The biological family and the shadow family have elements in common. There are significant ties and issues with both families.
There is also a third family, specifically designed for healing. It is not possible to describe this third family or to understand what exactly it means, yet just metting a member of this family for a few seconds can allow you to understand it all. Then you are likely to forget everything. Only when you get tired of forgetting things may change for you. Then you realise that your primary task in life is to get to know this third family.
The quest for this family may be the sole purpose in your life.
