Wolf:
Think about the Gra’s statement that he would have walked across Europe to meet Ramchal. If Ramchal had given him advice, do you think he would have taken it? I would think so. So it’s not necessarily just a chassidic thing. If you had stood in line to get the Chazon Ish’s blessing and he gave you advice, wouldn’t you do what he said?
Is R. Yaakov Emden a big enough tzaddik that if he says something is meritorious that I can do it?
