The Buddha refers to klesas, impurities; the egoist is always in search of something to brag about or to feel hurt about.
Just watch the mind - for what its goes on searching, then the coverings, the avernas would reveal themselves.
There are either incomplete acts, or impurities; or the third is called ghaya avernas - beliefs, opinions, ideologies, knowledge coverings. They don't allow you to know; they don't give you enough space to see.These 3 coverings, when dropped lead to "nothingness".
