I'm skeptical of "non-dual self knowledge". Maybe the subject-object distinction "is an illusion" but it seems like a necessary one. Would morality exist without a subject-object (or subject-subject, meaning two invdividuals) distinction? What would human behavior look like? How could we distinguish between a violent crime and a kind act? How could we make judgements? By what standard would an enlightened person who has dissolved the subject-object distinction prefer to be enlightened than not?
