I’m part Creek. Now, realize I grew up far from any semblance of native culture, and am probably not the best person to be speaking here. My mom is fullblood, but was also raised in the standard ‘American’ way. Most of my information comes from older relatives when I was a child and from my own research. So, YMMV. But I’ll try:
In the Creek culture specifically, grief is something that must be given a voice. A ‘funeral’ in Creek tradition involves family members and consists of singing and chanting, usually about the deceased’s activities in life and his/her personal philosophies, and expresses hopes that their journey to the otherworld will be safe. Sometimes, spirits are asked to intervene in the case of an unexpected or violent death to help the deceased understand they are no longer tied to the earthly realm or to their family. Promises are made to the deceased that they will not be forgotten, and all their quarrels with the living are forgiven, so that their spirit will not be tempted to return. Offerings in the form of tobacco twists, traditional foods, and jewellery are sometimes made in order to placate the deceased. Family members may enter a period of mourning in which prayers and chants are said for the soul of the departed. Fasting may be undertaken. The house must be cleansed and incense must be burned in the rooms. I understand that the deceased’s belongings were often destroyed, but this is most likely no longer the case.
Extreme grief may be expressed in several culturally mediated ways, among them the cutting off of one’s hair, the singeing of one’s hair, wounding oneself, or seclusion from the community.
After the ‘funeral’, there are no graveside visits, as cemeteries are traditionally held to be sacred places in which the living are not welcome, and the presence of a living person is offensive to the spirits. There are traditionally no gravestones or monuments. However, this tradition has probably almost completely died out except in small traditional communities, and I’m sure for the majority of Indians, a Western funeral with headstone and graveside visits is common.
For the Creek people, death is not to be treated as a subject to be avoided, but it is also not something about which to joke or speak lightly. Deceased family members are often spoken and remembered, and it is seen as important to pass this information along to all family members, specially younger ones. Grief is a very private thing, which must be born individually by all the bereaved, but is lessened by the traditional aspects of remembering the person’s life and accomplishments. But as in some European traditions, it is considered unwise to ‘wish back’ a departed loved one. This can keep the spirit from its journey, and may bring more grief to the deceased and guilt to the bereaved.
I hope some of this information has helped. Taking a culturally-oriented stance is admirable, but there really are some human constants. We all miss our loved one who have died, we all feel a little bit guilty about their passing.
