I have experienced many "dark nights of the soul" as I've evolved my relationship to the spiritual/divine and attempted to define what I am. I know how painful and scary it can be.
A fear that I still haven't completely shaken is not wanting to "drop truth bombs" on others who aren't prepared to hear it and possibly couldn't survive their own "dark night of the soul" if they aren't ready to hear it. Kinda like opening a flower before it has bloomed. That can be a bit patronizing, though.
Then I think, maybe I'm the universe speaking to them in this moment because they are ready to hear it. I'm the rain or sunshine that can prompt the flower to bloom. Good luck to them.
Most of the time I keep my mouth shut =)
