"Awareness is the key" : is what any of the spiritual guru would say. Is there any loss when there was nothing that is mine : not any at all. We don't exist forever, nothing else does, its all a game. A game of life.
What we see is provided to us to play the game. We dont own them though we perceive it so. When we attach our identity to these objects, losing them is misery and suffering. We are in constant search of newer objects to attach to.
Take this analogy, while you play a video game or a sport we get tools and objects to play the game it doesn't belong to us. We enjoy playing the game and losing means playing again. Same goes with life, this life time if we don't get the game we play it again till we realise the game of life and then the game ends.
So right now: "Life is beautiful and play the game" :)
