It's easily understandable why a person must have a Rabbi to ask questions to in matters of halacha (a posek). If I remember correctly, many mefarshim explain one of the 2 statements of "asei le'cha rav" in Pirkei Avos to mean just that.
My question is: Is there also an idea of having a single Rabbi as your 'go to' person for matters of hashkafah and middos related issues and idea's? Can a person ask around about non-halachic matters and choose what to go by on a case by case basis (which is not allowed when it comes to psak halacha)?
