“Are you proposing the above as sufficient positive evidence to substantiate your proposition? Or is it merely sufficient for one who is already a Chabbad Chassid (such as yourself), whereis a non Chabbad Chassid (such as me) should accept the proposition based on a leap of faith?”
Look, technically I should tell you that by looking at the Rebbe’s neshama, you can see who he is etc. The problem is that we are not holding at that level. Tzadikim can see who is holding where, and who is a Neshama of Atzilus here in this world, but I havent reached that point, and assuming that neither have you.
So the best evidence we have of who a tzaddik is, is from what we can discern, speech and action (body language as well), also where his interests lie etc.
The neshama can sense when someone is completely batul to Hashem and you can get a glimpse through stories of people’s encounters. Also learning the tzaddiks Torah can reveal allot. Both of these are available. There is a great book called My Story, that came out last year, about people’s encounters with the Rebbe. Its available to be bought and read.
By me, simply learning the Rebbe’s Torah shows who the Rebbe is. The miracle stories and open ruach hakodesh just add atop of that.
