What are the symbolic aspect of each head of Ravana from Ramanyan...........?

I don't know what Ramayana is saying about Ravana. But as per the knowledge that I got from Baba (The Supreme Father), the character Ravana itself is symbolic. After Satyug, Thretha and Dwaparyug the moral down falling of mankind from dieties to man (Narayan to Naran) become complete. His dispositions were predominantly dominated by five vices namely : Lust, Anger, Greed, Attachment and Arrogance. So five vices of Males and Five vices of Females constituted Ravan. Now we are in the empire of Ravan. Now all of our destination is to remove all vices and as a symbol only we are celebrating "dus hara" and burning effigy of Ravan.
