Vijay Dashmi

Dussehera is made by joining of two words "Dasha Hara" which means controlling  ten bad attributes within over self. 

Even "VijayDashmi" is Hindi translation of "Dasa Herra". It mean "Victory over ten evils" within us. 

Ravan having ten heads is a analogy to describe his having following ten evil attributes with in his head & personality.

As per Bible there are seven deadly sins. These sins are redefined & prioritised as per changing times by Vatican Church.
