“May my teachings be…like storm winds upon vegetation.”
~ Deuteronomy 32:2
Moses charged the people to continue following his teachings after his death.
Why compare them to something negative?
Although hurricanes are destructive, your average storm wind doesn’t damage plants – quite the opposite – by pushing the stems and stretching them to their limit, the wind actually strengthens them and makes them grow better.
So too Torah wisdom; although it pushes our boundaries and stretches our minds, it strengthens us and makes us grow.
The things you find difficult usually benefit you.
