Why? Because life is nothing but passing the parcel game. Played just for fun of it. In life whether you are in or out. You can't keep anything with you.
Actually the ball (parcel) is The Life-force, that dynamic energy which passes through you. In life you can't keep anything with you for longer than the time, as you never know when the music of life will stop. The energy which is getting passed will end at you.
You might be any kind of player, slow or quick, teasing one or frighten one, wishing to get out first or want to win or want to play the music and enjoy the show, and many many more. Energy, the life-force can stop at anyone. If you are the one making others the play then to be unbiased, equality are things running to your hand as you are somewhere controlling the energy.
A game where we want to give something. That to without keeping or hoarding it. At the end the parcel never belong to you. That energy never was yours and though you felt like it's yours. In whole or nature this pass the parcel games with multiple forms of energies going on. Some in form of matter and some in form of energy in motion and some in form of just thoughts and ideas and maybe more. That's where the first difference between game and life begins. Second is the parcel never remains the same in life, unlike the game.
Yes, what you give comes back to you. Sometimes many many times more. As we say what you sow you ripe. Sometimes it doesn't come stops at somewhere else and you need to wait for game to restart. You are not dead or out, you are still part of that circle. Continuously reciving and giving. Reciving air, taking oxygen for the use and giving back CO2 and passing air back. The cycle continues whether it's air, water or earth. Forms changes, essentially all remains the same.
There is one more difference too, the person doesn't get out like in a game if parcel is with them when music stops. In real life person is out when it looses the capacity to give. That also means not able to receive. The life becomes more beautiful when person finds giving is love. Though there is a big catch there in Giving. Maybe some other day and other time it will be given and passing will continue.
As I reflect on Giving, all above thought I pass on. Which started with one idea of giving is equal to passing. Leading one point to another and building those connection, relations, this whole is made.
Same way we are that tiny dot in the circle of nature. So enjoy the moment you received and what you give. Enjoy the moment when someone else recives and gives. Make your own strategy to enjoy the most out of the game.
