About Lashon Hara (negative speech)
It is not so much that we need to be taken out of exile.
It is that we must take the exile out of ourselves.
What is exile? It is the belief that there is some place outside of G-d.
And that in that place, there are forces stronger than G-d.
And those forces will not allow you to do what your soul came here to do.
Fear no thing, no force, no being other than G-d. Do that which you must do as though nothing stands in your way.
Then you will have taken yourself out of exile. And G-d will complete the job.
