From the "Agony of Azhdahak":

O thunder! loud and proud

How does it feel to roar your sky-breaking bellow and receive a faint shudder and a sigh in return?

Cursed be those who are blind to power unless it serves them!

Cursed be men, women and children who see pain and turn their heads!

My hate is strong!
My hate is pure as a mother's love
    As a father's awe
    As a son's disrepair who had to watch all that he ever
    loved die and could do naught 

I hate for once I loved!

Thus began the becoming of the beast, for he was shunned from his kin.
