They falsely believe that to be spiritual means they will die with love in their hearts or some other misconception. They can't tolerate what they really feel because it doesn't conform to their ideas about practicing all these years. It is sad, because practice is and has always been about being fully human. This means both screaming and loving, and loving the screams. This is certainly an important lesson of death.
Death is the great equalizer.
Like toothpaste through a tube, death squeezes the past out of us as we are dying. The dying often try to square themselves with their lives through life review. They will talk endlessly about the areas of their lives which still hook them and ensnare them in the past. We sometimes hear of exceptional phenomena occurring around the time of death. There is such profound mystery to death.
