I think I understand Franz when he was able to ‘transfer’ his love from one lover to another.
He could feel an affinity for someone where he felt his life depended on this one person... to end this love was to forfeit his life.
But when this person withdrew their love he preferred to love another this way, feeling all the things he felt, over death.
If you dedicate the entirety of your essence to writing down your feelings, you may start to find they become bigger than one person, bigger than yourself.
What engages your senses in the moment of this lifetime?
