One way of Knowing
Sometimes our flame goes out but is blown again into instant flame by encounter with another being. --Dr. Albert Schweitzer
Once the realization is accepted that even between the closest beings infinite distances continue, a wonderful living side by side can grow, if they succeed in loving the distance between them which makes it possible for each to see the other whole against the sky. -- Rainier Maria Rilke
I made a slight change to both quotes above. I removed just one word from each: human. To me, the insights Schweitzer and Rilke present are more true when seen in this inclusive way: accepting that all beings are capable of loving, of being intimate, of kindling the flame of life in the heart of another being -- even one of a different species.
