I think that "judgment" must not be confused with "opinion", because even if you meditate for years you still can't be neutral in life's situations. We all have a natural opinion about things, and it is normal. The "lower self" will going to transform his opinion into judgment from the moment that his opinion about something affect his acceptance and/or patience about others. To think that someone is a "lower self" compared to you is ok, but to manifest this by avoiding or treat differently shows that maybe you are worse than the people you judge. We have two objectives in life: self-actualization and HELP others to self-actualize. Humility is the key.
