It is in all big philosophies/spiritualities/religions:
What you resist will persist / you become what you hate / judge and you shall be judged.
If you hate/resent/judge something in others (he is too lazy!) it means you hate that element just as much in yourself and this hate will thus keep you from being balanced, because you will:
This is a built in genius design of life: It will keep giving you anything you dont love(accept/allow), until you learn to love(accept/allow)it.
Learn to love/accept (on an emotional level) all aspects in yourself and others
If there are parts in you that struggle to do that, first step is to love/accept those parts.
You may notice that you keep having the same frustrations throughout your life. This is because you have not learned your lesson on an inner level. . Moving away from the problems in the external world will only provide a temporary resolve - soon again you will find yourself in the same frustrations in that new job or new country or new relationship. Life will patiently repeat those patterns again and again until you give up fighting and resolve them with love.
What are you ashamed of?
What do you judge in yourself? In others?
Are some people “hopeless losers”? If so, what part of yourself do you still see as a hopeless loser - and why did it not work for you to talk badly to that part your entire life?
As you speak to others, you speak to yourself - even if it is subconscious.
People who mistreat themselves or others are suffering. They need empathy and help - not judgement and hate.
