To collect his brachos is always worthwhile, and our Chazal stated clearly, “??? ??? ??? ????? ???? ?????”. It does not instruct us to seek their prescriptions
This is what they call a straw man. There is nobody, and I mean nobody who goes to a Godol for actual medical advice rather than to a doctor.
One may not assume that the Gadol is responding from a wellspring of ??? ?????, even if that is something we have reason to believe is possible.
An Adam Gadol, of the type that I would want to speak to, would be mature enough to know what he knows and what he is capable of answering. I wouldn’t advise someone on something of which I am not sure. It doesn’t make a difference how much Ruach Hakodesh, if it is a mixture, or if he happens to be well versed in the topic. If he tells me then he knows that he can advise me.
Yet, one does not have the freedom to rely on such ??? ?????, unless all other forms of ??????? have been exhausted.
This does not mix with Hishtadlus. It has nothing to do with that. If you got an answer then you got an answer. Hishtadlus would mean that you shouldn’t wait around for an answer. What does it mean not to rely on Ruach Hakodesh? If you know that it is from Shamayim, who exactly are you outsmarting?
