The problem with teaching from an enlightened perspective is that it is a perspective that is inaccessible to most people who are not in that transcendental perspective. Just think about parents losing a child and a guru coming in and saying "there is no death" or "everything is perfect". Instead of that creating awakening, it is going to enhance the opposite. It is going to cause pain. It enhances the distance between the two perspectives instead of closes the gap between the two perspectives.
