Sometimes God is pleased to heal him by means of your medicine; sometimes not--he dies.
When he is cured, you take the credit of what God does.

I do the same.
Sometimes God grants us rain, sometimes not.

When he does, we take the credit of the charm.

When a patient dies, you don't give up trust in your medicine, neither do I when rain fails.

If you wish me to leave off my medicines, why continue your own?
M.D.I give medicine to living creatures within my reach, and can see the effects, though no cure follows; you pretend to charm the clouds, which are so far above us that your medicines never reach them.
