present existence of all kinds before becoming humans or animals used to be something else. This is not separated from kamma, whether it is a part or present, good or bad, before or after. Kamma can not occur at same time. It can not be put in perfect order and is limitless. The effect of past kamma is incalculable and even exceed the present existence. All good and bad deeds give effects. Though the effects may not occur at the same time chronologically, the outcome will definitely happen due to the cause. Whatever the outcome is each of them will occur to be definitely.
