We can predict with amazing accuracy the effects of these planetary combinations.
If a malefic dasa, or difficult time period is seen, you can take precautions such as working with planetary mantras, performing specific acts of charity designed to generate balancing karma, or wear the gemstone remedy (upaya) from a gem prescription.
