Your karma is simply your deeds.
What ever you do voluntarily or involuntarily is your Karma or the cause of Karma. Also known as charge karma Whatever happens to you is the result or the effect of your past karma. Also known as discharge karma. Every cause has an effect Some times effect is immediate, sometimes it can be a long while before the effect is felt. It is believed that every individual is born with set of karma, which explains why some of are born rich or poor. Every moment whatever happens to you is the result of your past karma. Whenever you act with selfish motives you are doing karma for which you have to face consequence sooner or later. If you can believe that in reality you are a spiritual Soul , not a temporary human form then as a soul you are not the performer of the karma. It’s your human form and associated ego which is the root cause of the karma.
