Recall, reflect, remember, and pray.
Remember loved ones our departed and, in a spirit of true charity, remember other departed souls who may have no one on earth to pray for them.
Consider the reality of purgatory and those who, despite being so close to heaven, must prepare to enter it. The Church teaches that these souls can benefit from your prayers for them, and that their prayers, in turn, can benefit you.
Remember, Station by Station, Christ's Passion and Death for those souls, for all souls, for your soul.
Pray that the same Christ, the conqueror of death, will soon welcome the souls of your loved ones, as well as the souls of all the faithful departed, into the Eternal Banquet.
