Pain is the feeling. Suffering is the effect the pain inflicts. If one can endure pain, one can live without suffering. If one can withstand pain, one can withstand anything. If one can learn to control pain, one can learn to control oneself.
The one word love means too little for what it is. It doesn't communicate even a fraction of the feelings involved. Love. The word is not enough for what it is. Love. Love.
There are never words for the strongest of our feelings. There is just the pain that we cannot share. Pain we must all feel alone.
