Spirituality
Death confronts us with an ultimate loss and the fundamental unknowable. Great religions have examined these issues for thousands of years. Death is universal, yet every death is unique. There are no rules, and no easy protocols. Yours will evolve depending on your life experience, values, and the help that your receive. In this way, you have already been taught, and will teach those around you, and help them prepare for their turn.
From our own experience, we can say that clergy of all great religions are used to dealing with death and are almost invariably willing to help you through it should you wish it. As well, the connection death can create between all those involved has an intensely spiritual quality.
