I am having difficulty choosing a Yeshiva. Did the Rebbe ever give advice as to how to choose one?[1]

Indeed, the Rebbe wrote the following to a certain student in a similar situation: Even if there are individuals in the Yeshiva who don’t act appropriately, including if such individuals are found amongst the management of the Yeshiva, nonetheless, there is no foundation for this to be a clause to affect and influence one’s level of learning and diligence, as why should one punish himself and be lax in studying the wisdom and fulfilling the will of God because some individual is not acting appropriately. Nonetheless, it is self-understood that when there are less matters of disturbance, then naturally a person is able to learn with greater diligence. Furthermore, the sages state that a person should always study in an environment that his heart desires. Now, there are a number of yeshivas in Lubavitch and although all of them study Torah and Chassidus with fear of heaven etc. nonetheless, the order of the yeshiva is dependent on the rest yeshiva and the Mashpia etc. Now, it is known with the sages state that God created people with different opinions and every individual has their opinion and their path of holiness even though everyone is working towards the same goal so the students reach perfection in study of Torah and fulfillment of Mitzvos. Based on the above, the answer to your letter can be found. My advice is that you should choose one of the Yeshiva’s of Lubavitch in which you feel that it will be easiest for you to study Torah diligently, and furthermore and mainly, you should contemplate and all that was written above and resolve in your mind to learn and perform because this is the wisdom and will of God and His command and then you will see that most of the difficulties are imaginative, and on the contrary, the more you add in diligent study so too the challenges will be diminished until they are completely gone.
