a little bit of spiritual potty humor

Physically, we know the importance... actually, the necessity... of getting rid of waste... preferably on a daily basis.

The same is true emotionally, socially, psychologically, mentally, spiritually: I suggest it is just as important and even necessary to get rid of waste.

Anal retentiveness: trying to control the necessary and natural functions holding it in not letting stuff go.

It's not good for you.

What isn't doing you any good any more? What is no longer useful? What, if you keep it, will turn toxic and eventually make you sick and even die?

What needs to be flushed away?
