I saw a programe about this on national geography channel.They did research on it scientifically as well,putting all sorts of wires and machines to the person's brain who spoke in tongues they didnt understand while in prayer and they discovered that just as they had done research on possession by negitive spirits in which they show sceptics going to a place where they they find between rocks lots of black magic done ...in the sense that there are all kinds of really ugly and eeky bottles and jars with claws and body parts of animals ,threads ,poppets etc and the priest(who they take along with them )opens up all these jars and boxes and says his prayers etc releasing all the damage done by negitive spirits.the sceptics while watching this first feel a headache,then nausea and finally faint.
on the contrary,when doing research on the ones speaking in unusual languages while in prayer,they discovered that these people were possessed by the holy spirit.
A sage once told me that in the brahman ,there is already script of sacred words and chants written(like the sanskrit chants which are so powerful and ancient and produce such powerful positive vibes and results).I presume that when one makes a connnection ,some could be reading those scripts and giving out powerful vibes which hence make everyone arund feel whole and peaceful.
