The ancient Romans celebrated the Lemuria on May 9, 11, and 13. During these times they honored the wandering ancestral and family spirits. Many modern people still make the trip to the cemetery during the Memorial Day weekend for the purpose of putting flowers on graves, a way of acknowledging and remembering deceased family members.
However, it is not necessary to go to cemeteries to honor your ancestors. In your long lineage, most of your ancestors will not have been buried near you, and some will have been cremated and their ashes scattered or their physical bodies lost. This day of remembrance is not to honor a decayed physical body, but to honor the bloodlines that led to your existence.
Set up a spot within your home as a temporary ancestor altar; choose a setting that will not be disturbed for at least a week. On this altar place what pictures you have of deceased family members. If you have no pictures, print out their names on a nice piece of paper. Arrange a small vase of fresh flowers near the pictures. Burn lavender or rose incense daily near this area.
Sometime during each day of this week, go to your remembrance altar and talk with your ancestors. Don’t forget to call upon the ones so far back in your lineage that you never met them. burn a white candle there for at least an hour each day.
Perhaps you have a few immediately deceased family members with whom you didn’t get along. Most people do. If you find their spirit energies causing problems (and some will do this), simply remove their pictures until they can behave themselves. This may sound silly, but it works on most spirits. They want to be remembered and acknowledged not put out of mind and sight.
Often those family members with whom there was the most friction will be of most help because they may want to make up for bad karma. Occasionally, a very few will be incorrigible and will have to be denied admittance to your home.
Each day, ask your ancestors for advice and help. If you meditate near this shrine, you may well find yourself visiting with loved ones. And remember to think about and call upon them throughout the rest of the year, especially at important occasions. You can light candles, or set extra places at the table for them during seasonal festivities such as birthdays, thanksgiving and Christmas.
