From five years old, if a child is trained to call all woman as "Mother," naturally his culture is different. Because he has learned to call all woman as "Mother." He has no other idea. A small child, any woman comes before him, he knows "(S)He is my mother." So this was the practice. That is not only religiously, but morally, it is so good, to look upon all woman as mother. That is the system still in India, any unknown woman who has no introduction with you, (s)he is addressed "Mataji." Address her. She may be just like daughter or granddaughter, but one would address, as a respect to the woman, as "Mother, Mataji." This is Indian system. Now some rascals have introduced "Bhaginiji, sister." But that is not shastric. In the sastra, all the woman, except one's wife, should be addressed as "Mother."
