Can humiliation be liberation?

Do you think that pointing out ego fixations publically serves to free students of their egos? What do you think are the advantages, and drawbacks of this teaching method? Why do you think it works or does not work? In more ancient times, it was very common for aspirants to be repetitively humbled by teachers, in an attempt to free them of ego attachment. That is a less common tactic nowadays, but I have seen it still show up occasionally. I had two experiences in which a teacher has pointed out my ego fixations in front of a group, leaving me to feel humiliated. The first time it happened I ended up more cemented in my own suffering. The second time I was able, later in my own meditation, to take a perspective on the experience and see how my false-self was keeping me stuck in fixation. Now I find myself standing more firmly in my own truth, but less confident in the teaching I was given. Does anyone have a similar experience?
