It is well known that King Janaka and other Royal sages attained moksha as well as wisdom in their earlier stage only by performing the prescribed duties. (Though release is vouchsafed for knowledge alone, still the wise do practise duties for securing enhancement of Bliss in Heaven.) Besides, even for the sake of guidance to the world, it is fit that you should do your duty.
