In many cultures mourners would be hired to help the remaining grieve, because it is not considered a good thing to continue to hold on to the one who has passed. We must let them go and move on. Now, anyone who has lost a loved one knows that you cannot 'get over' their death in 40 days. But, it is important to not drag them down to remain here on earth. They are on to another journey beyond what we have here on earth. Usually & hopefully, a good 1 1/2 -3 years takes away the initial great difficulties, and leads to an acceptance of some kind, making life easier to handle without the loved one.
Time heals all wounds, but never forgets. Memory Eternal KG!
