Written by Rabbi Meir Kahane
(taken from "Perush HaMaccabee", Rabbi Kahane's commentary on the Tanach)
"If there arise a matter too hard for thee in judgement. then thou shalt arise , and go up to the place which the lord thy G-d shall choose. and thou shalt do according to the sentence ." (Parshat Shoftim, 17: 8-10)
We can learn out from the words "if there arise a matter too hard for thee.", that if you have a question regarding something you don't know, then you must ask. But if you are certain of the answer, do not ask, but rather make the halachic decision on your own. And it is unfortunate, that today many have become robots without common sense, who turn to the rebbe for everything, turning him into idol worship, so much so, that they disregard any other rabbi, and even turn heretical in disgracing other Torah scholars. And this seems to be what the Ibn Ezra is saying on the verse (11): " 'and you shall observe to do according to all that they inform thee' regarding something too hard for you".
"Be careful, lest you forget the covenant of the Lord your G-d, which he made with you, and you make a carved idol, or the likeness of anything, which the Lord thy G-d has commanded you." (Parshat Vaetchanan, 4:23)
This verse is difficult to understand, for it should say at the end, ".which the Lord thy G-d has forbidden you." It seems that the interpretation is like this: Do not make a carved idol, or the likeness of anything, including of things which G-d commanded us. In other words, don't make idol worship out of things which you admire, such as the Holy Temple, Sefer Torah, or a great rabbi, for this too, is idol worship. This is why the verse continues, "for the Lord is a consuming fire, a jealous G-d". In other words, worship must be exclusive to G-d only; and He will not tolerate any competition or partnership in worship.
"And Asahel pursued Avner, he did not deviate from the right or left from behind Avner" (Shmuel 2, 2:19)
One who pursues a positive goal, it is proper to see it through to the very end, and not deviate from the right or left (as it says in Parshat Shoftim "do not deviate from the right or left"), but adhere to it despite all the difficulties. But such clinging to a goal is only positive when that goal is a positive one -- only then one must cling to the path and not deviate right or left. But if the goal itself is a negative one, of course one must deviate from the evil (as it says, "don't deviate from the right or left, remove yourself from evil" (Mishle, 4:26). And here, Asahel is clinging to a negative goal, by chasing Avner in a war of brother versus brother.
There is a sad and dangerous phenomenon today, and it is: the growing tendency of students relying completely on the rav, or the "gadol", going after him like a blind man in the dark, not deviating right or left -- without the willingness to think for themselves. This personality worship essentially prevents the student from independent thought, and is dangerous for the student and for Judaism. Instead of striving to serve and worship G-d, they accept upon themselves the service of the rebbe, and if he says "white" and tomorrow "black", the student will follow him, and will boast that he obeys his rebbe and adheres to the mitzvah of "not deviating from the right or left". Indeed, this is a dangerous and bitter phenomenon, which turns the Jew from a thinking individual to a robot.
Of course, one must obey the psak halacha of his rav, but when it comes to "hashkafa" (political, world view), one must analyze and think things through, and he must even argue with his rav if something seems incorrect, or he has counter sources. And if he thinks his rav's halachic decision was mistaken, he should approach him and ask him to clarify things, and not just accept it. And even though he must obey the decision as long as his rav sticks to it, it is incumbent upon him, in any case, to pressure his rav, over and over again until either his rav agrees with him, or he is convinced that his rav was indeed correct. And it is a pity that our generation has become one of "mouths that do not speak, eyes that do not see".
