An unknown traveler, weary and far from home, may stop at a hogan along his way assured that he will be welcomed. Although he is a stranger in the sense that he has never been seen before, he will be taken in and cared for. That is the Navajo way.
A Navajo is never a complete stranger to another Navajo. It has been a tradition since the beginning that The People identify themselves when they first meet by the process of clan relationships and family order. Through this identification process, a Navajo knows exactly where he stands in relationship to all The People. If he is from the Salt Clan and meets a family that belongs to that clan, he is immediately considered a part of that family. The mother will call him her son, and he will be introduced to the family as a brother.
If he meets a distant clan that has no relationship to his, he is still identified through his clan and associated with others of his clan who live nearby.
The clan system also serves as a guide for marriage. People in the same clan cannot marry, nor can they marry if their clan is related in some way, although they may be apart from each other. Some clans have branched off from main clans and therefore are related. The clan system keeps The People unified as a family.
The hogan is always open to others. When a visitor comes, he is invited to stay awhile. As he visits and talks, his hosts prepare a meal and feed him. It might be just fried bread and water, but the visitor will be grateful for such hospitality.
