That brahmacārī rules and regulation are there in the Śrīmad-Bhāgavatam, that he would go door to door for collecting alms for his spiritual master, and address every woman as mother, from the very beginning. 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 "Mātājī." Address her. She may be just like daughter or granddaughter, but one would address, as a respect to the woman, as "Mother," "Mātājī." This is Indian system. Now some rascals have introduced "Bhaginījī," "Sister." But that is not śāstric. In the śāstra, all the woman except one's wife should be addressed as "Mother."
That is the instruction by Cāṇakya Paṇḍita, a great politician moralist. He says that, "Who is learned scholar?" He was himself very learned scholar, but he is giving definition of learned scholar. What is that? Mātṛvat para-dāreṣu: "Anyone who sees all woman . . ." Para-dāreṣu. Para-dāra means other's wife. Para-dāreṣu. Mātṛvat. Not his own wife, but other's wife. So except one has got one wife, and all others, others' wife. So mātṛvat para-dāreṣu, to treat and see others' wife as mother. Mātṛvat para-dāreṣu.
