Dear boy, just as it is the water’s nature to make me wet, so it is the nature of the Scorpion to sting. And just as it is the Scorpion’s nature to sting, it is my nature to save.

Funny thing about this is the word ‘dharma’ can either refer to an inherent quality of something(water’s wetness) or a duty that one has taken upon (a doctor treating the sick).
