Hi,
I have somewhat of a silly problem, but it's my current obstacle to meditation and after googling this quite a bit, and trying to solve it on my own, I just wanted to get some input. I've been meditating casually on and off for over a year, but recently decided to get more serious about it. I am following the Mindfulness In Plain English guide at http://www.vipassana.com/meditation/min ... nglish.php. Overall, it's a very useful resource, but it doesn't say anything about where to place your tongue during meditation. In many other places, I have seen that people suggest placing the tip of the tongue against the roof of the mouth, or against the place just behind the front teeth, or against the teeth themselves. This is done mostly to decrease salivation and swallowing during meditation, but also perhaps to connect some energy pathways of the body.
I have tried to do that, but there are several issues. One, it's not very clear where exactly and how the tongue is supposed to be placed, because different places have different specifics and sometimes use different terminology. The second and more important issue, is that my tongue does not naturally stick to the top of my mouth. It might stick for a while, but eventually, as meditation goes on, it starts moving downward. Because of this, it seems like to make it stick, I have to apply pressure upward, and this both tenses up my mouth and also distracts me from the meditation itself, as I am often thinking about whether the tongue is getting loose and so on.
After that, I decided to just do meditation with my tongue in the loose position (just free in the mouth). But now, I am always worried that I am not doing it right, that after a while, the saliva will start flowing, or that the tongue is too loose in the mouth.
So I guess my question is, is this stuff really important or am I just concentrating too much on unimportant details? Can I stick with the tongue being just naturally loose or should I try to touch the roof of the mouth (and if so, how do i keep it from sliding off)? I appreciate any responses, especially from people who maybe also went through something like this.
