The same sefer quotes the following letter written by the Imrei Emes zy’a of Ger regarding the danger of machlokes:
‘My brothers and friends, I want to make one important request of you. I promise to help anyone who gets involved in this and helps make it a reality. It pains me to say it, but the amount of love and unity we have for each other is lacking. Sadly, in one chasidus, we find many arguments. That is not good. We should be united with genuine peace and we should be helping each other, physically and financially. If we do this, we will be able to be strong in all areas of Yiddishkeit because everything depends on unity. If you help strengthen our unity, it is certain that Hashem will help you in all ways, especially in parnassah. This what I request of you.
I ask my beloved ones, the people of our group, to work to improve the peace with the charedim and chasidim who travel to various tzadikim, and especially with those with whom there exists a ‘separation of hearts’. I ask you to be united and connected with all of them…
If you obey me and try to increase the unity and peace, Hashem will help to fulfill your desire.’
