There can be all kinds of pain; physical, emotional, mental.  Pain can be based on the real or imagined.  It can cripple or be lived with.  All in all, in order for it to be a help, a compass for where one might be leaning into for growth or awareness, it must be noticed.  

This does not mean I have to understand my pain entirely.  I am underlining this.  It means, to acknowledge it is the step to doing something about it.
