Is there suffering upon this new earth? On our earth we can only love with suffering and through suffering. We cannot love otherwise, and we know of no other sort of love.
~ Fyodor Dostoevsky in THE DREAM OF A RIDICULOUS MAN
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.
