Plenary indulgence for the souls in Purgatory
which can help to remit the temporal punishment due to sin for those who have died in a state of grace, can be obtained throughout the octave of the All Saints Solemnity (November 1-8).
* * *
Plenary indulgences, which remit all temporal punishment due to sin, must be accompanied by full detachment from sin.
A Catholic who wishes to obtain a plenary indulgence must also fulfill the ordinary conditions of an indulgence, which are sacramental confession, reception of the Eucharist, and prayer for the intentions of the pope. Sacramental confession and reception of the Eucharist can occur up to about twenty days before or after the indulgenced act.
