Heart...
Life is full of hill, mountains, boundaries, whatever!! It's like a game. To elaborate... It is like a game of pool.
All starts off in order. All the balls where they are supposed to be. You only have to do one thing, break them up. That is when the chaos starts. Now it is the time to search. To search for the best shot that will lead you to a victory. This shot might not seem like a lot, but if this shot is the wrong one then all your hopes vanish. You take it... It's not over now though! Time for another shot. This time there is more than one opportunity. Which one do you choose? The one that is guaranteed or the one that is risky, but yet SO very exciting. As soon as that choice has been made then you have to start over again. Which one? Which path? Do you take the shot of ease, or of slim chances. Shots are made, shots are missed, but no matter what. All of them WILL make it to their destinations, but the win might not always be in your favor. What do you do? Sit and stare at a blank table of cloth wondering what you should have done? Or do you just rack them back up and start it again?
What does heart have to do with any of this? You might hope to have the easiest game in the world with the best shots, and the best decisions. Sometimes it might happen, but chances are sometimes you'll slip. Is this reason to put the pool stick up forever. NO!
Now relate this to YOUR LIFE!!!! If you don't reach those points in your life where you question all that you are and have been then how will you EVER find out who you are to become? If you don't walk in the valleys then how will you know how good it feels to sing on the mountain?
Heart is the strength inside our being that gives us the courage to take the shots that are questionable, to rack the table up again when all was lost, to dig our way out of the valleys to see what light looks like again, and to find our way to the mountain top and sing forever.
Heart... it keeps our eyes searching for the light we can't always see... |
