@hyena: Auuugh! You just don't ask the easy questions, do you?
"It depends on the tradition" *vague understatement of the thread*
Most believe in reincarnation of some sort; taking a stronger view to "shedding the skin" rather than just dying and leaving what they're familiar with. The snake shedding it's skin is a common symbol associated with pagan funeral rites; with references to "rest and regeneration". As the death of a part of the Earth, death is not taken personally (for example, a god did not choose this person to die); but as a means of benefitting the cycle of birth, death and rebirth - this extends from the soil to the trees to humans themselves. It is commonly accepted that ALL living things must go through some dramatic transformation in order to expound on what they have already been. The circle of life is an ongoing process, and change is welcomed for new opportunities to grow.
Not that anyone cheers death onward - some gather for healing circles to prevent death from happening prematurely. To pray, to ease in passing, to cure; or in my tradition: to convince the chaos that caused the illness that not all fundemental Wills and/or Goals are accomplished.
A "Sacred Space" is created for prayer and/or magic to work within; a place where the living and the dying may convene with the gods, if necessary.
In the USA, I am not aware of any pagan burial grounds; as most pagans opt for cremation here. For pagans in any other country I'd be completely unfamiliar with burial grounds and/or practices. If a pagan was involved in a group or coven, the coven may keep the ashes to continue working and communicating with the deceased in ritual or magic. Some wish their ashes to be released and scattered. Some groups perform a "Soul Release" after aquiring the remains prior to cremation, although I'm not quite educated on the process or reasons for that itself if the deceased is already, well.. deceased. It would seem that a release would only be neccessary for the living - as a "wake" for the departed. There are no set rules for the duration of time between death and cremation and/or burial.
Just as life is celebrated, the dead are celebrated as well: a practice quite similar to the Day of the Dead celebrated in Mexico. The day set aside for this purpose is Samhain, or October 31st. Pagans gather to honor not only the gods, the final harvest and the death of Summer, but the deceased from this plane. Feasting, dancing, music, other happy pagan goings are prevalent to this day to welcome the ascent of the darker time of the year; combined with the darker times of our lives. Some groups have tables set with plates and food solely for the deceased; so they may join the celebration.
As for my personal views on death; it will happen when I am finished here. If only I knew when that was.
Hope I'm making sense.
