The matter could not be settled.finally they soon approached their parents to get justice.lord Shiva and Parvati heard both the sides and then lord Shiva had an idea "children," he  said to them,"let us settle it this way you have to go around the world and one who comes back first will be considered to be the right one the other one wrong !Do you agree?"

"yes ! Yes !!Agreed both of them Kartikeya always rode a peacock and was very fastat it while 
Ganesha used a little rat for riding.Kartikeya was sure  that he would win the race because his peacock was much faster than the rat.Kartikeya immidiately  jumped  on his peacock and rode very fast as he could.

Ganesha  first had a look at his big  stomach and then at his  little rat.He was sure that he can never win the race.Then Kartikeya was already away with his peacock.And  Ganesha just sat down there thinking and suddenly he had a bright idea.He made lord Shiva and mata Parvati sit together and quickly went arround them three times.

 Soon.Kartikeya came on his peacock after travelling  arround the world successfully and told Shiva-Parvati proudly," here I come ! I won and looked at Ganesha "No,"said Ganesha,firmly,"our parents are the mother and  father of the world,so going arround them is just
like going arround the world!

I have done it three times but you have done it only once and that makes me the winner! And Ganeshalooked at lord  Shiva and  Parvati,"am I right or wrong?"he asked them.

"Ganesha is right",said Parvati to Kartikeya," he has won the race ! " Hearing that Kartikeya lost his temper and thought that mother was partial to Ganesha.

In a feat of anger he took an oath,"I shall neither  look at my mother's, nor any  woman,s face in  the world ! "and  Kartikeya   kept his word,he never looked at the face of any women in the world.So,in many temples of kartikeya,women do not enter.
