Hearing from people who have gone to India, it really is something else spiritually, and there are great saints and yogis walking about amongst it all. It's just a whole different atmosphere in the air thick with spiritual energy. I have heard some out of this world accounts from people who've gone there.
On the other hand there would also seem to be an equal abudance of fakers and those eager to make quick and easy money fooling people, like the many so called "Godmen" of India who perform feats easily explained by science or by illusion.
At this point I don't feel like I've experienced a ton, but enough as far as a sampling of abilities that I think stuff like this is absolutely possible with enough training and dedication. A matter of sensing and taking in the right mix of energies, or there are apparently other ways through yogic techniques and lengthening the tongue to reach a point upwards where drops of divine nectar comes forth that bestow bliss and take away hunger to yogis immersed in meditation. I'm not so sure such a thing is just going to happen automatically once the tongue touches that point though.
My dream actually would be able to master pranic intake and bodily heat regulation and be able to just wander the wilderness without a want or worry, meditating from place to place for a year or more

I feel like I already have a solid lead on mastering heat generation via a particular hand mudra.
Anyway that's my long response lol. I've just been thinking a lot about details and how abilities and senses work lately.
