So I’ve read a bit about this practice of folding the tongue back into the soft palate and eventually into the nasal cavity in order to induce mental relaxation, sense withdrawal, meditation, etc. It seems like a pretty important practice, regardless of where I read about it - a lot of meditational techniques seem to recommend khechari mudra to be done throughout.
However, most sources mention that the frenulum needs to be gradually cut over time in order to stretch the tongue into the ‘full’ form, where the tongue is vertically pointing up into the nasal cavity, which I imagine stimulates some area of the brain or something along those lines.
My question is whether or not it is possible to get the tongue into this position without having to cut the frenulum, in other words through gradually stretching it back over long periods of time. I'm not about to stick a knife anywhere in my mouth but I have no problem folding my tongue back and stretching it. I can easily touch the uvula at this point but that's as far as I get.
Does anyone here have experience with this practice?
Looking forward to your comments.
