This is something you bring with you when you are born to the Earth. It is always present but gets ignored as you go through the momentum of this life, with all the trivialities and non-dramas, which are only as bad as you want them to be. But when you listen to your inner self with all the wisdom of the ages and the learning of other lives and other worlds you will begin to understand the meaning of wanting and needing.
All the negative thoughts create a shadow that affects everybody, for thoughts are living, more so than the deed, and can poison the whole world.
So you must think twice and twice again before you even make that remark or begrudge anyone anything. If you join in gossip, try to put a kindly word in, for love is the only blockade against these thoughts that bring envy and self pity; you will never find happiness and contentment while you harbour thoughts against others.
Send loving thoughts and say a prayer. Think about healing their soul. This can be achieved by absent healing and also works on the sender and the receiver.
