In effect all we need to know is this key – we have three possible masters: the highest is our mind, thinking without any biases, which as it’s impossible (see soon) the only way we can achieve this, is to consult an expert in a field and follow their advice (if they are a friend, hence looking for our welfare) for though they too are biased when it comes to themselves, they can be unbiased and objective when it comes to you – for the other two masters are our instincts (as we see with drugs addicts, food addiction etc. etc. the person has no ability to control their self-destructive instincts) and of course, the worst is our ego: the narcissistic tendency to seek supremacy and far worse the anger when feeling put down and even worse the jealousy of others who feel o.k. which is the reason for the insane predilection of antisemitisim, bullying, antiamericans etc. etc.
