All of us are solitaries: we are born alone through the birth canal into the world and time, and we die alone. No one can enter our interior experience, or its continuum with the outer world we call community. Solitude is the human condition, the universal vocation to be human. It is the willingness, with Love indwelling, to go to the heart of pain to find new life and share it with the world even though you may be separated from it physically. It is from this commitment to be focused through the narrow gate of solitude that self-emptying love is outpoured, and the heart of the community, the heart of its pain, is transformed into the heart of joy.
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.
