The ultimate difference between depression and the Dark Night of the Soul is that depression is usually self-centric, whereas the Dark Night is philosophical in nature and is accompanied by existential reflections such as “Why am I here?” and “What is my purpose?”
Also, when depression ends, not much changes in your life in terms of your beliefs, values, and habits. However, when the Dark Night of the Soul ends, everything in your life is transformed, and life becomes wondrous again.
I often hear people speak of the Dark Night as some kind problem they have to “fix,” or something they “went through a long time ago, that is now over, thank God.” But what these people thought was a Dark Night may have just been a glimpse of the darkness within them, especially when they speak egotistically about it as if it were a badge of honor.
A true Dark Night of the Soul leaves a long-lasting impact on you – it changes you completely. When you exit a Dark Night, you will discover that something is always taken away from you (for the better), such as your beliefs, your perceptions, your former meaning in life, or even in rare cases, your ego. The metaphysician Ananda Coomaraswamy put it this way, “No creature can attain a higher grade of nature without ceasing to exist.”
Have you ever seen a butterfly begin to emerge from its cocoon? It must struggle in order to strengthen its wings. If someone frees the butterfly from its cocoon prematurely, it won’t be able to fly because its crucial tempering stage will not have occurred.
The same is true for trees. Trees need wind in order to build their structural strength to stay upright.
