Well dear PJ,
am not an expert but am a YOGI, its a practise of evoking of our internal energies(actual terminalogy is not known) , a self realization process, connecting all to one place… i.e. body, mind, and soul… bringing them close.
which means 3 r there but seen only one, can feel 2nd one , with those 3 rd one can achieved.
-> i dont know what u want ask abt swami, u mean a teacher? swami mean a teacher , guru in Indian terminology.
-> lowerbrain waves means , keeping our mind in peace place, taking out the negative thoughts , even more positive attitudes , So when these 2 comes under control, the BRAINWAVES comes lower.
-> out of body experiance, what i know is letting the body, mind and devine to be at one stage. (accorind to devine mind gives commonds to body and according to commonds of it body functions goes, so letting these all connected).
YOGA CAN CHANGE THE ENTIRE LIFE of urs and the world tooo.
OOM SHANTI SHANTI SHANTI HI.
