Padre Pio was a great benefactor of the Holy Souls in Purgatory. Souls from Purgatory often appeared to him, to ask for his prayers.
One night there was lots of noise coming from Padre Pio’s room. The priest in charge of the monastery thought that there was a party going on in there.
He called out to Padre Pio for an explanation. Padre Pio told him, that the voices that he could hear, were actually the souls of soldiers, who had been delivered from Purgatory and who had come to thank Padre Pio for his prayers.
