There’s a healthy amount of trepidation I feel as a Rabbi preaching a sermon on medical issues in a congregation with plenty of doctors. So this is my obligatory disclaimer: I am not a doctor. Any advice dispensed from the bimah is not valid medical advice. This is where my rabbinic authority ends.
When the Torah tells us to ‘sh’lach l’cha’ or ‘lech l’cha’, to send from ourselves or go into ourselves, as in the case of Abraham’s calling, we know that something transformational is about to happen.
