What is the negative aspect of ego transcendence?

If one talks about ego, one has to distinguish two aspects of ego: positive ego and negative ego. Positive ego is ego that has enabled us to feel like individual human beings, distinct from the mass, or earlier, distinct from the tribal collective mind. This aspect of ego is essential, because only through self-individualization can we fully understand our task in this world. Only through the acknowledgment of "I" as individual can we grow to become truly human.

Negative aspect of ego is the one you are probably asking about and there is nothing negative about its transcendence. You have to overcome your own greedy desires, fears of losing control and also, fear of death. Negative ego likes to compete and be better than anyone else for the purpose of self-aggrandizement. It says: "I am indestructible, I am the best, I am the smartest, no one is better than me." This is something to abhor. It is essential not to think of yourself as anything greater than any other human.

If this is not pursued, we all know about the consequences.
