To conclude the discussion on whether a person must travel faraway for reasons of hishtadlus, the answer is very clear: There is no such thing that a person should have to run to distant lands to attain money. This is a clear mistake, and there is no such thing.
But if a person sees that min HaShamayim he is being guided to travel to distant places, he should understand with clarity that he goes there not for parnassah, but for another reason. He’s working there, because he’s fulfilling his shlichus in t his way.
