Guardian Angel: Indulgences have an enormous power. This is a wonderful work of God what you are doing for souls with indulgences. Abide in this practice and spread it, because people do not know and do not want to seek indulgences. And if they knew the gratitude of souls, they would do much more. Heaven agrees with those who pray for the souls [suffering in purgatory]. The Lord loves them very much and their suffering hurts Him, but they must suffer what they must, unless you help them.
