Why in North India, Ravana is burnt on Vijayadashami day? This is done to symbolize Lord Rama killing the 10 headed demon Ravana. Good over evil! What does the 10 heads of Ravana stand for?
The ten-headed Ravana can be interpreted as the ten negative things that every human should keep n check:
Kama (Desires)
Krodha (Anger)
Moha (Delusion)
Lobha (Greed)
Mada (Over Pride)
Matsara (Jealousy)
Manas (Mind)
Buddhi (Intellect)
Chitta (Will)
Ahankara (Ego)
Wish you all a very Happy Vijayadashami!
