Yes, we are all sorry to lose a loved one. Yes, we will miss that person. Yes, there will be a void. But let's think about what that person did while he or she was alive. How many people have not benefited from their kindness, their charity, their advice. These are some of the positive reasons that will not make us forget this dear departed.
I say departed and this word is sad, it is true. But let us face the truth. We are all sad to lose someone we have loved so much and we want to keep him among us, if not concretely, at least spiritually. This will be our way of keeping him alive forever.
Remembrance, memory, thought are so many aspects that can make a mourning a little less painful. We are all grieving and with good reason, but let's be content to see the good side of things. The deceased is no longer there physically, but he or she will remain with us forever.
The saying we use in this case is BAROUKH DAYAN HA EMET, that is, BLESSED IS THE JUDGE OF TRUTH.
