When a delegation of rebbes, i think ger, and others, met the chofetz Chaim, they came out and said they had never seen a pereon reach his madregos withoit toras chasidus.
This is because all paths of Torah lead to the same place. They lead us to Hashem, as an adam hashalem. A person can be an adam hashalem as a chosid,a litvak, a sefardi, a temani, a hungarian or a yekkie. All roads lead to Hashem.
Rav Akiva eiger says this about the “machol latzadikim” that Hashem will make leasid lavo. All of them will point to Hashem and say “this is the Hashem that we hoped to” each tzadik will recognize that their path led them straight to Him, just as all ends of a circle are equidistant from each other, with no tzadik being oser to Hashem than the other, as long as they followed their mahalach to its fullest.
I have the utmost respect for an emesdige chabad chosid, those who reject god-in-a-body and dead messiahs, and live according to the mesorah of the rashab, rayatz, etc….fhere are plenty such people in Yerushalayim. One of my rebbeim also broke off from Lubavitch when the last rebbe became the leader.
