The Mother is kalpvruksha( the spiritual tree which fulfils all the desires). Father is invisible space, which has lifted the entire universe. A mother is a place where the children open their mind and to get peace and satisfaction of desire. They did not know that the invisible father is around of their mother and hearing them. Every desire of stubborn children fulfils by father & Mother. Happy mother's day without forgetting the father as the father is the reason for the existence of mother & vice_versa.
