Why don't I wash my hair and take baths more often than I do? (Not that I need them but "inquiring minds" have wondered).
Because I could take a million baths and not ever feel clean from how much humans have dirtied themselves.
So unlike the many guilty modern male and female "Lady Macbeths" I do not feel the compulsion to scrub and to scrub; I just endure being among the moral and mental s*** until someday, I hope, people regain their senses and their spiritual cleanliness.
People, you can vacuum and bathe everyday and spray every disinfectant known to humankind, but until you cleanse your souls you will never be nor feel truly clean.
