Seven I of soul. 7 roles of the team. 7 faces of the soul. 7 types of character (english edition)

In Russian, the word “family” means “seven I”. They often write the word “family” through seven: 7I. But what is this ‘I’, what are these ‘I’s, and why are they exactly 7?
A Family is not just a team, linked by marriage and kinship. A Family is definitely established, brierty team. Relationships are not built immediately. Everyone needs to “put” himself in the team, to take his “position” to find his “place”, get the role. In total, the team has 7 “places”, roles. That’s why family is 7I.
