This document summarizes the key points about forgetting sorrow from a chapter in the book "Practical Religion Vol. 2". It makes three main points:
1) We can never truly forget our deepest sorrows, but we should remember them in a way that brings blessing rather than bitterness. Some people dwell perpetually in the shadows of past grief and fail to appreciate current blessings.
2) There is a duty to forget our sorrows in the sense of not brooding over them and letting them stunt our growth. We should turn from graves to our present duties and look forward to future joys rather than back on losses.
3) Sorrow should spur us to new earnestness in service rather than inactivity
