Answer: All your desires and thoughts are your enemies.
Usually people around you, who don’t really worry or concern you, don’t mean much to you. But it’s the people who seem to be your enemies or those whom you hate, they are the greatest help for your advancement. We should only understand how to use this kind of help.
If they are your friends in the group, you have to turn them from your enemies to your beloved friends. It makes no difference whether someone hates you or whether you hate him. Usually you are the one responsible for bad relations, but you have to change things from hate to love.
It’s not simple at all. Start calculating things in this opposite direction internally and you will see what intense work it involves.
