The site states :
This classic meditation program has been extensively used and studied by biofeedback therapists. In a study conducted by The Other 90% in San Francisco, using a 24 electrode EEG showed that an astounding 87% of research subjects, who had never meditated before, entered the Theta State of advanced meditation.
Using that audio and doing vipassana at the same time, I was able to feel sensations from the base of spine traveling upward which i believe is kundalini.I freaked out and stopped doing that.
Can you point me to a book or resource for beginners so that i can understand it without freaking out.
If I use the audio will i stop learning or improving? I know i need to stop using it as it is not the real thing but i feel it will speed up things a litttle.
