Bad karma is the spiritual debt one has accumulated for one's mistakes from all previous lives and this life. It includes killing, harming, taking advantage, cheating, stealing, and more. On Mother Earth, when you buy a house, you take out a mortgage from a bank. This mortgage is your debt to the bank. You pay every month for fifteen, twenty, or thirty years to clear your financial debt. In the spiritual realm, if you have bad karma, you may have to pay for many lifetimes to clear your spiritual debt.
