The greatest form of love, is the love that consumes. It trades breaths of your life with happiness, It consumes you, weakens you, kills you moment after moment... When you achieve that level of perception, you will gladly trade your lively moments for your addiction of love that consumes. There's no greater pleasure and no better way to die.
It consumes you in a good way. Imagine if one day you give all the love in your soul to your partner, then decided to sell everything even your house and give this money to the poor. Then you went to the hospital donated your organs to the sick. Your love for the world was the motive. By the end of the day you will be lying sick, weak, homeless and broke. Nobody will take care of you now, but you never waited for anything in return from the world. You will have nothing with you except the love that consumes. You will die at the end of the day, Right? That's of course an extreme example of the love that consumes. Normally it kills you slowly, day after day. But you're happy. Sometimes even your partner can't understand or even notice the love that consumes that you give and even them will consume you as well. You're still happy, That is the love that consumes.
