Most people will not dare tell you the truth about yourself, about your flaws and weaknesses, because they are afraid of losing your services or making an enemy of you. So, behind this amiable, tactful attitude lies self-interest, and as a result, you retain your faults, which only worsen over time.
True Initiates behave differently. They have no personal interest, they are not afraid and they have nothing to lose.
Since they know the truth, they already have it all, and so they show you your imperfections, especially those that cause you harm and keep you in the lower regions. They dare to tell you what makes you ill and unhappy.
Why? Because they are actually your best friend, and they want to give you the means to correct your failings.
