I think there are two kinds of lies, conscious lies we do fully aware, some are white and maybe ok.
And there are also lies that we hide from our selfs – we are unaware of hidden in our blind spots. We all have those unless we are fully enlightened and saints.
I have at least at times experienced that I see something in my self – where I have thought: “Ups … I did not see that, I was kidding myself there.” I do not think it is that last time I have experienced that in my lifetime – hope not at least.
