People are easily swept off their feet, mesmerized, hypnotized, influenced, excited, robbed of morality and rationality by the world around them because they worship their physical senses and the crooked realities they bring them.
And this, obviously, leads them to be unconscious and to envy greedily, to try to feel superior and put others down. This you must understand about people, ALL people, including the people you care about, the people you least expect, and perhaps you unconsciously do it as well.
This appears to be a sickness in most people when they do not feel whole inside, so they seek to fill their emptiness to feel better about themselves and their lack of integrity. Some do it consciously, some others unconsciously; however, it is certainly in all unawakened human creature to do this in their different ways, seeking their own self-gratification.
Because people compete with one another, but they do not know it most of the time; and until they bring illumination into themselves (which it might never happen in most cases), their behaviors and intentions are erratic and concealed to their own awareness.
So, one must understand that they do this, and they act out, and they pity themselves at your expense, because of the great void and unhappiness buried deeply within them. This is the sick game they play.
And to understand this gives you the depth and insight into all your relationships. And relationships are the very evolution of situations and people you have to master in your journey to be happy; so you may look into people’s unconscious behaviors and gain patience for your own harmony and illumination.
