Expecting suffering may predispose you to being surprised by feelings of joy. If you expect suffering, you will anticipate suffering and you may suffer from anxiety as you wait for your suffering to occur. Expecting pleasure is no better than expecting suffering, because when you are not feeling pleasure you will feel disappointed and begin suffering. If you don’t expect pleasure or suffering, you are left expecting nothing.
When you expect nothing, you are prepared for what comes. If suffering comes, you experience it as it happens. You do not worry about it before hand or concern yourself with it when it is gone. When you experience pleasure, you are happy. If you’re experience is neither positive or negative, you are not disappointed or fearful, you are just there. There can be quite peaceful.
