The soul was separated. The soul guarded his father's grave for thousands of years just to prevent his father's grave from being disturbed. After a thousand years, he sensed the existence of the soul and understood why he could not return to the physical body. After the death of the physical body occupied by the soul, the soul took the soul back to a thousand years ago, just to prevent his father from suffering the pain of his absence. However, he did not know why the soul allowed the soul to occupy the dominant position in the physical body.
