Have Videos and meditations tapes available that guide people in a religious and non-religious way. These could be related to making peace with the mistakes in your life, confessions and other themes. Some could be interactive, where other patients, personnel or family members take part. This is so people can die in a more peaceful manner and let go of guilt or other issues before they go. These meditations should be full of compassion and peace themed messages. Meditations of people relating near death experiences may also be helpful if geared toward the person listening. Meditations of gratitude for what a person contributed to this life may also be helpful .
I really think that many people would like to let go of secrets and other information and it would be great if they had someone to tell and possibly either help them to have the courage to "make amends" or even just a place to leave information in case someone comes looking for it, for instance a child who was put up for adoption.
Ceremonies can be created also and volunteers or family members or friends may participate to help the dying person let go of old fears, unresolved issues or whatever. This may bring more peace not only to the dying but others who witness it.
