Nature ensures joy and pain to everyone. When you are only expecting joy in your life, you can’t handle pain and any painful episode will seem to be even more painful to you. However, when you are mentally prepared for pain, it can’t make you suffer easily. If most people suffer, it is because they are always expecting pleasure and happiness in their life. Hence, when suffering knocks at their door, they are unprepared for it and suffer immense pain.
