Its so hard to miss your dear ones. The pain of separation is unexplainable. One day of life without your dear ones is equivalent to a year. But when you meet your dear ones after a long period of separation, that happiness is unexplainable too. All the pain you underwent during the period of separation becomes meaningul and vanishes before that happiness of getting together. This feeling of love and affection is beautifully expressed with the words "The Pain of Parting is Nothing to the Joy of Meeting Again".
