A Buddha's Knowledge of the Past, Present and Future

Other languages
The karmic tendencies on our mental continuums have the abilities to give rise to a variety of karmic results. Before we are Buddhas, we can validly cognize, or at least know with presumption, that these abilities exist. Based on that understanding, we have choices of how we will act and thus we can affect which result will arise from these karmic tendencies. Buddhas are certain of which result will actually arise. Thus, we limited beings can affect what is not yet happening, while Buddhas validly cognize what is not yet happening without predetermining what will be presently happening.
