Mantras to speed up body functions

Can I use a mantra to speed up some body functions like hair growth for example?

I don't believe that you can. You see, mantras are more for focusing mental intent. Like making yourself intend to have a lucid dream, they aren't really for speeding up and bodily functions really. I'm pretty sure things like hair growth or something like that pretty much just happens on it's own, I don't think there is much that you can do about it and mantras probably will not help. Sorry if I sounded rude or anything, just trying to answer as best I can.

I'd like to see an experiment with it! Try it out and see what happens - we all know the power of the mind, placebo effect, etc. In this same way is the reason mantras work in the first place - I see no reason why focusing your intent on growing your hair can't stimulate something to make it grow faster!

"I have a full head of hair"
"Every day my hair gets longer and fuller"
"As I dream my hair gets thicker and longer"

and before you know it you could have a full head of hair, or a kick ass beard :P

Mantras are cues to your subconcious. You can program your body to react to certain mantra. But I doubt you can do that. If you want to take account all the mysticism that exists, you should be able to heal wounds with mind alone etc. Even if possible, it should prove itself insanely difficult.

But in reality, the best way to use mantras is to program them to affect your mindstate. One mantra for focus, one for relaxation, one for preparation of physical workout. That kind of thing.

What about doing it indirectly? For example if you have a cut on your elbow and you want it to heal very fast, healing during sleep happens more rapidly during delta sleep. You get into delta sleep because your brain starts producing slower brain waves. So could you use a mantra like "I have longer delta sleep" or "When I sleep my brain produces alot more delta waves" or "when i sleep My brainnproduces slower brain waves"? If it works you will have longer delta sleep and your cut will recover faster. Or for the first example your hair will grow faster because hair growth occurs more rapidly in delta sleep too.
What are your thoughts?

If it worked that'd be the way. So I think.

But as said, I think it is almost inhumanly hard to have that kind of body control. In theory it is all possible and there are many legends and lores suggesting that with strong willpower you can even change the colour of your eyes.

But that said, good luck trying. I always enforce that kind of thinking ,though. Visualize and will my body to heal faster etc. Maybe it helps, most probably not.

I've been trying this out for the past couple of days and it seems that there has been a great increase in my hair growth. You guys might be skeptical about this but it seems like it's working rather well.

Maybe. Or maybe you are not qualified to proof that it is actually growing faster or that the actual reason is your mantra. Either way, if you are looking hair growth be happy :P

I have mantras to pump me up to the fight and I believe that I can stretch my limits because of it. If I didn't have that metabelief then it would be pointless.
