The womb of the mother symbolizes the mother earth. As is the seed of thought sown in it, so is the fruit that it yields. You can not expect mangoes by sowing a need seed. So, the mother should foster good thoughts, good words and good deeds. Only then can she beget virtuous children. Today we find many children having bad qualities and wicked conduct. The reason for this can be attributed to the bad thoughts of their mothers.
