The mother knows the family in which the son is born and the father who has begotten him. From the time of conception the mother beings to show affection to her child and find joy in him. On the other hand, the Scriptures hold that the issue belong to the father only.
माता जानाति यद्गोत्रं माता जानाति यस्य सः। मातुर्भरणमात्रेण प्रीतिः स्नेहः पितुः प्रजाः॥
