ok, im really not the greatest at explaining things that i do.
ill try.
i had a teacher many years ago, when it was totally wasted on me..haha..
he got me to do many hours of mantras, alone, vocally,... and then after a long time, he said that i was ready for the "real mantra practice", which was taking the mantra into the heart, and vibrating/projecting it throughout the whole body with internal silent "sound", and i had to feel the different mantras vibrate in different areas on my body...
i never REALLY felt it as i was supposed to...
now with my studies in a different area of all this , i finally understand what it was all about. I started doing internal vibration because using my voice kept dragging me to the physical reality of my body, when i was trying to do my practices in a different form - not astrally though.....and i found that i didnt feel the same incredible surges of energy when i used my voice as i felt when i took it inside.
wow this is SO hard to explain coherently!!!
so i basically use my WHOLE body, not just the physical part, and you know, my lungs do feel it, and i do feel the exertion, but the overall effect is incredibly energizing, in spite of the exertion. It takes a lot of focus.
it wasnt that easy , it took a while for it to come naturally.
i hope ive explained myself.. i never talk about this stuff, but sometimes its good to share experience... id love to learn what others do, and id especially love to find out ive been doing it wrong way all this time..haha!!!
