EFT can be great, especially if you're applying it to yourself, and you have a lot of patience. But if you don't have two hours to work on your anger - or you don't even know that you're angry in the first place - then other things could work better for you.
One of them is called the 'TAT' pose, TAT standing for: Tapas Acupressure Technique.
I like TAT for a few reasons:
1) It's much simpler to do than EFT. You simply hold three points at the bridge of your nose, and place your other hand over the back of your head.
2) It actively includes G-d in the process, and gives Him some space to work His miracles and magic in your sub-conscious psyche
3) It can solve issues at a much deeper level, even if the person doing the TAT pose has no idea what, specifically, is the problem.
The only drawback I've experienced with TAT is that the 'pose' is very powerful, and not everyone can hold it for long. But even when people can't hold it for the minimum minute officially required, it still seems to work to dissipate negative emotions and feelings, and leave you feeling changed and somehow 'lighter'.
In spiritual work, as in life, the more effort you put in to the process, the more you get out of it. I'm not suggesting for a minute that doing TAT will solve all your problems instantly. Life's not like that. But what it does do is open your subconscious up to G-d, and to hope, and to healing, in a very gentle, subtle way.
And once that's happened even once, on a profound level it suddenly clicks that things - even very painful, difficult, impossible-to-cope-with things - don' t have to continue hurting us for ever.
G-d has put all types of healing into the world. We just need to connect to Him, be willing to spend even 10 minutes 'going within', and He'll do the rest.
