Only when we understand our own darkness can we have compassion for others. When we reach the bottom and can see how we have unconsciously made mistakes despite our intentions to do well, we can understand how others are just as human as we are. The human condition can be a huge challenge for some souls to undertake; it breaks us down and makes us do things to avoid the pain of living on earth.
Some have drifted so far from source that happiness is just a word on paper and pain is all they know, their world is true darkness. For those who have traversed both worlds, we understand, we see it, we have lived it and survived.
Love is still the answer, there is no other way.
