Young children show their personal traits and characteristics from the beginning of their lives. Some of these show as qualities and some of them as faults. They both need attendance.
The qualities need to be cultivated and the faults need to be reversed and molded to reveal their creative, self-serving side.
Every child is born with a basic personality, which is unique. It is much more than the sum total of the parents' qualities and faults.
The Self carefully chooses a long "line" of a soul-family tree, which best reveals the needs of the soul and desires of the spirit. Then, the Ego has the difficult task of "doing its best with what it has", without having all this information on the surface of the mind.
