Allow me to elaborate. We eat and drink out of love for our bodies much as we breathe in air. We take care of those we bare into this world out of love until that love fosters into a whole person capable of doing this themselves. We prolong our own lives out the love we have for them. The hole we develop inside ourselves is from a lack of love. No amount of things will fill this hole. What causes the hole, you might ask? Our ego. It lies to us and tells us we must be separate to have value and that things can instead fill it. Ever bought a smartphone? I bet if you're reading this, chances are you have. How did feel when you saw a better one that did 30 things yours did not? Not good is the common answer. Unless you impulsively bought the first thing you saw and could afford, chances are you looked into your purchase. It was sufficient when you bought it. The only reason is that you're assignment of status to the quality of things you have has been equivilated to your self worth. This is a downward spiral. You're ego will tell you that you deserve only the best things when in reality you only deserve love. Next time you feel empty, remember that you just need to fill that hole with love. Its a more fulfilling action that is its own reward. Our brains actually release an array of pleasure hormones when exibit generous behavior towards others. And i like pleasure, especially the free kind. And the best part of love is that it is in fact free. Its when we let our ego take hold and tells us the greatest lie, that we slowly starve. We hurt, we break, we just run out of steam. Love yourself, then love the world. Try it. What do you have to lose? Be well.
