How to hold your level even when helping the sunken

HH Rabbainu has at least two lessons addressing how to not get dragged down when doing kiruv.

One is actually this week's Parsha (VaYaishev). See Likutay Moharan volume 2 Torah teaching 63.

The other lesson is Likutay Moharan Torah-teaching 59.
