Dark night of the soul
Whenever a word is overused, it is most likely being misused, and over time, it begins to lose its meaningfulness. For example, we often refer to a fleeting feeling of depression or a period of confusion, as a dark night of the soul, but neither of these things qualifies as such. A dark night of the soul is a very specific experience that some people encounter on their spiritual journeys. There are people who never encounter a dark night of the soul, but others must endure this as part of the process of breaking through to the dawn of higher consciousness.
The dark night of the soul invites us to fully recognize the confines of our egos' identity. We may feel as if we are trapped in a prison that affords us no access to light or the outside. We are coming from a place of higher knowing, and we may have spent a lot of time and energy reaching toward the light of higher consciousness. This is why the dark night has such a quality of despair: We are suddenly shut off from what we thought we had realized and the emotional pain is very real. We may even begin to feel that it was all an illusion and that we are lost forever in this darkness. The more we struggle, the darker things get, until finally we surrender to our not knowing what to do, how to think, where to turn. It is from this place of losing our sense of ourselves as in control that the ego begins to crack or soften and the possibility of light entering becomes real.
Some of us will have to endure this process only once in our lives, while others may have to go through it many times. The great revelation of the dark night is the releasing of our old, false identity. We finally give up believing in this false self and thus become capable of owning and embracing the light.
