After a few weeks living with this there is a noticeable difference in my ordinary disposition, demeanour, and general everyday attitude and conduct.
It works! you can change yourself with this procedure. See I Thess 5:17. That I have never achieved, and I'd be amazed if I ever did. But people do. Some of the most creative people of our age have done it and still do it (don't ask for examples).
Living with a mantra like this has a complex result:
1. It seems to deaden the mind. Admittedly I use it every night at bedtime, and it has wonderfully improved my sleep habits. Wake up? Resume, and blotto.
2. It sensitizes your mind; you see more, feel more, do more. It goes by the title of 'the new man'. (The unknown author (below) refers to it as being 'oned with God'.)
Result 2 is like a knife edge between self centered thoughts and sleepiness. But it happens, consistently.
Re self-centered: if this is not a problem to you, you're wasting your time reading this. I venture to suppose that it's a problem to a great many of us. (It often descends entirely into pure blood selfishness; not a problem? God bless you; you're very rare.)
