I don't think there is an easier and more powerful mantra you can use these days.
Ho'Oponono came into my life a few years ago. It touched me as being so special and profound. Four little sentences that you can eventually boil down into two.
The Simplest Mantra You Will Ever Know
I love you.
I'm sorry.
Please forgive me.
Thank you.
I spent a whole year repeating it intensely. It was an ongoing mantra. And the results we stupendous. relations cleared up. Knots unfolding from situations.
There's no need to go into too much details here but suffice it to say there is a big difference between traditional Ho'Oponono and its modern iteration. I'll focus on the modern interpretation that came about when Morrnah Simeona distilled the modern version spearheaded then by Ihaleakala Hew Len, alias Dr. Len who co-authored Zero Limits with Joe Vitale.
The great thing about modern Ho'Oponono is that anyone can do it, any time, anywhere at any moment in time. In fact, the more you do, the more you get a feel to it.
For those who don't know about this precious jewel, think of it as a Universal mantra. The order of the sentences doesn't matter. You can arrange the sentences in whatever order matters.
Focusing on the outcome is a no-no. Don't do it. Just repeat it, fall into an introspective frame of mind and let the magic begin.
