Too late I loved you, O Beauty so ancient yet ever new! Too late I loved you! And, behold, you were within me, and I out of myself, and there I searched for you.
~ by St. Augustine in Confessions, X, 27
If you maintain a feeling of compassion, loving kindness, then something automatically opens your inner door. Through that, you can communicate more easily with other people. And that feeling of warmth creates a kind of openness. You'll find that all human beings are just like you, so you'll be able to relate to them more easily. That gives you a spirit of friendship.
