A life without love, without the presence of the beloved, is nothing but a mere magic-lantern show. We draw out slide after slide, swiftly tiring of each, and pushing it back to make haste for the next. 

– Johann Wolfgang von Goethe

Love is that condition in which the happiness of another person is essential to your own.

– Robert A. Heinlein

 Love knows hidden paths. 

– German Proverb
