All, everything that I understand, I understand only because I love. - Leo Tolstoy

All, everything that I understand, I understand only because I love. Everything is, everything exists, only because I love. Everything is united by it alone. Love is God, and to die means that I, a particle of love, shall return to the general and eternal source.

– Leo Tolstoy

War and Peace, Book 12, Chapter 16, Prince Andrew’s thoughts.
