How do you interpret the story in the gemara, beitza 36b, of Abbaye and Rabba and the mill?
Something like..
Where Abbaye has a halachic problem. He asks Rabba, Rabba gives a lenient answer using a loophole (which was of benefit to Abbaye).. But Abbaye disagrees with it, he thinks halacha is stricter.
Abbaye disobeys Rabba, and regrets it, and says he should have followed his rav.
I have heard some rabbis say, this , is proof that you have to follow your rav.. Even if you want to be stricter than him, you cannot.
others have said.. This gemara shows that you are bound by your rav`s answer, but only if you ask him.
I have heard rav kahane say you are bound by your rav`s answer, but only if you ask him.. (in answer to a question of - who is your rav - and does he agree with you..)
Is this an aggadic thing that we shouldn`t be so sure we understand.. It is very radical. And just one gemara. And I don`t think the RAMBAM sees it halachically like this, or he would have mentioned it in his mishneh torah (I assume it doesn't).
What is it teaching.. Do we have a tradition on what it teaches?
A strict reading of it, would stress more parts of the story, and say it teaches you that (if you ask your rav and he gives you an answer then ) you cannot or should not be machmir(stricter than) your rav. Perhaps the reason is it may embarass him e.g. especially if he has many students.
