"A fight between equals, like the collision of one unbaked pot with another, destroys both."
-- Maxims of Chanakya
I have no special reason for citing this. I just opened my copy of this at-times-lame at-times-clever book, and it fell open to that quote, under the original Sanskrit (which I would reproduce here, but I doubt you or I have the right fonts installed).
Maybe that's YOUR horoscope for the day!
