As Ravan had 10 heads, Does each head have individual names? Did Ravana got all names for his heads?
How he had got 10 heads?
Ravana was born with ten heads.
Having been thus accosted, the girl, O Rama, after a length of time brought forth a very terrible and hideous offspring having the form of a Raksha, having ten necks, furnished with large teeth, and resembling a heap of collyrium, with coppery lips, twenty arms, huge faces, and flaming hair. On his having been born, jackals with flaming mouths and other ferocious beasts began to gyrate on the left. And that god showered down blood ;and the clouds uttered forth harsh sounds.
The names of the ten heads are not mentioned in the Uttara Kanda or Ramayana. I presume that there are no names to them.
Due to these ten heads, he got the names 'Dashagriva', 'Dashakantha', 'Dahsaanana'. As he was a descandant of Pulastya Brahma, he was also called as 'Paulastya'.
And as in consequence of thy arms having been hurt by the mountain, thou hast uttered a terrific yell, which struck horror unto the three worlds and put them shaking, therefore, O King, thy name shall be Ravana. And Devas and men and Yakshas and others living on earth shall call thee Ravana terror to creatures. So, O Paulastya, which way thou wishest, and permitted by me, O Lord of Rakshasas, go thou.
I heard another story
The 3 bros (Ravana, Kum and Vib) do yagna to Brahma. But Ravana is not comfortable with yagna and feels out of place. He cannot focus. So, to impress Brahma and speeden the process, he cuts his own head and puts it into fire. Brahma, much too impressed, puts it back. Ravana repeats. Brahma repeats. And so they play on for about 10 times in toto. Finally Brahma, thinks ‘Enough is enough!’ and appears before them. Hence, Ravana is said to possess 10 heads!
Ravana’s 10 heads denote 6 shashtras & 4 vedas that he mastered in his lifetime.
His ten heads also represent 10 human emotions:
Kaam – Lust
Krodha – Anger
Moha – Delusion
Lobha – Greed
Mada – Pride
Maatsarya – Envy
Manas – Mind
Buddhi – Intellect
Chita – Will
Ahamkara - Ego
