That’s interesting, I wonder if it has an Indic origin. I know the thing about the long tongue is found as a yogic practice; Iyengar talks about it.
You just have to be clear about what you mean. The texts are as they are: nothing changes that. When I talk about EBTs, I simply mean the early strata of texts. Of course, we have to accept that not everything in the EBTs is authentic: the two are not synonymous. “Early” does not mean “original”.
