the slaughter of the buffalo demon by the goddess is one of the very oldest icons in indian civilization: it goes back to the indus-sarasvati valley. this is a reminder of the goddess worship that was widespread all over the world until patriarchal cults replaced them by force.
there are many mahishasuras today that need to be slaughtered.
may your new endeavors today be blessed with success! today is the day for new beginnings, including vidyarambham for children.
