“Likutei Moharan is not a sefer halachah. Whether or not thereโs a contradiction is irrelevant; itโs not comparing apples to apples.”
The question is: In Likutei Moharan it says ืืฆืืื ืืืืื ืืืืืช ืืฉืืื ืชืืื, happy always; while in the mishnah it says ืืฉื ืื ืก ืื ืืืขืืื ืืฉืืื, in Av we lessen ืฉืืื. How can R Nachman’s statement stand notwithstanding the mishnah?! Doesn’t R Nachman’s statement require always ืฉืืื while the mishnah requires sometimes no ืฉืืื?
The answer is that ืืืืืช ืืฉืืื and ืืืขืืื ืืฉืืื are not going on the same thing. ืืืืืช is a state of mind and ืืืขืืื is acts of ืฉืืื.
