These feelings detonate especially with love as we saw most often in our time: love because of superficiality, of determination not focus ... the love that may qualify too quickly "free". To compare with the absolute love that is here described by Zweig: do not we just as endearing hero certainly, but ultimately superficial? This new me thinking about the power of love, specifically human emotion able to make us move mountains. This news is deeply human, after all. And that's why it is universal.
As for the form, the Zweig: the quality of his writing is the feeling of power. We have embarked on an adventure that surpasses us and calling us both.
