Which is an example for karma

The belief in Karma is essentially the belief in whatever you do will come back to you. In other words, "what goes around, comes around".  Some examples of Karma are:1. If you help a beggar in the street, you will be helped when you need it. 2. If you steal a mobile phone, your mobile phone will be stolen from you. 3. If you mock and ridicule people with a disability, especially elderly people, you will develop very bad arthritis and will not be able to walk on your own.
