since it's 12:45 am and i've run out of brain juice.
here you go with a legend
Kalidasa, the greatest sanskrit poet's greatest work is said to be Kumarasambhavam, or The Birth of Kumara (another name for Kartikeya, hindu god of war, commander of the heavenly armies, and Lord Shiva and Lady Parvati's eldest son).
The work is actually incomplete. It's not that we haven't found it, it literally doesn't exist, cause Kalidasa hit writer's block (don't worry, the epic is still pretty great).
The legend part? Well the epic contains a porno consisting of Parvati and Shiva having sex, written in painstaking detail. Goddess Parvati got offended that a random human on earth was outing her bedroom secrets, and so she cursed Kalidasa with writer's block so that he never finished Kumarasambhavam.
