I see people posting about Karma all the time...and I don't think they know what Karma means. If you beleive in Karma, then you have to believe that you have had previous lifes.
So, when something bad happens to you...how do you not know that it was actually Karma being delivered to you for something you did in this life or a past life? And I usually find that the people claiming Karma will get someone to be fairly hypocrytical about the wrongs they had perpetrated against others.
To wish for bad Karma on someone is actually wishing it on yourself - because to wish for bad things to happen to ANYONE puts a deposit in your bad Karma bank account. Karma takes care of itself, to allow you to free yourself from angry and hateful feelings so you can move on. Also, to think that bad Karma has been delivered and to rejoice in it also puts a deposit in your own bad Karma bank account...because it is bad Karma to enjoy the bad things that happen to people no matter how much they deserved it. Karma is all about love and perpetuating love and the bad things take care of themselves.
Peace out.
