All religions and cultures suffer from sources that preach hate against the 'other.' Throughout history some have, tragically, practiced what their sources preached, while some have sought to dismiss or even counteract the hateful words of their sources.
It is the suffering of ambivalence: the murderous alternation between bitter resentment and raw-edged nerves, and blissful gratification and tenderness
Suffering is how Life tells you that you are resisting or misperceiving what is real and true. It is the way Life suggests that you are not in harmony with what is.
If to enjoy even an enjoyable present we must have the assurance of a happy future, we are “crying for the moon.” We have no such assurance. The best predictions are still matters of probability rather than certainty, and to the best of our knowledge every one of us is going to suffer and die. If, then, we cannot live happily without an assured future, we are certainly not adapted to living in a finite world where, despite the best plans, accidents will happen, and where death comes at the end.
