Letter by a Strange Hand (NWN)

Written in a strange but delicate hand, this note found alongside a key in the foyer of Castle Jhareg. It appears to be a riddle of some sort and reads as follows:

"The Three Paths of Justice

"Wary must be the Judge and straight His course, for His one hand is burnt by the fire of treachery and His other chilled by the ghosts of vengeance. The True Path of Justice lies with the Heart and Head for only with Reason can He determine the Truth and only with Compassion can He knows its Consequences.
