It is the really the sad truth that is reflected in this compilation of notes among these doctors. Sad because of what is stated in the points about regrets; not true ourselves, working too hard and missing the children/spouse's best years, not expressing themselves and so on.
What is even sadder that close to death, most still express self cherishing. Having not doing enough for others, their regrets are mostly centered on themselves out of their current suffering, loneliness, feeling of loss and fear of death. While there are some component of regret about not doing more for others, I doubt that the motivation is really about doing more for others. This is the result of living a selfish and ignorant life; of not doing more for others that cause their loneliness, fear etc and is expressed via regret. So we can see karma in action albeit the negative ones.
If we live a life for others, at the time near death, we would have very little to no regret. If we live a life for others, we would be content know we have REALLY done our best.
If we are spiritual, even better. Then we know that we have generated merits. We are content if our family and friends do not visit us often, we are content if they do visit us often. We leave behind everything and are ok. we have the insurance of Guru Devotion, merits and what we have done with a spiritually fruitful life. We understood refuge and karma; of contentment and renunciation; and of boddhicitta and wisdom and most important of others. We have confident, joy and we are relax. We look forward to another fruitful life.
That should be our aspiration and may we all engage in the effort for that.
