Shri Mataji: Vibrations are the feeling of the all pervading divine power within yourself on your Central nervous system. You can feel this divine power for the first time after self realization on your central nervous system ending up into your fingertips where the sympathetic centers are located. So you start feeling on your hand the universal language which is spoken by the hand the different centers. And thus you know a rapport is established between the spirit and yourself. Because when you ask a question about any fundamental problem you either get a cool breeze flowing into your hand or you just stop it. Sometimes you might get some blisters also if the person is suffering from some sort of a very great mal-adjustment. You might get numbness if the person is on his way to death or could be very freezing cold. So the hands start speaking as said by Mohammed sahib; that your hands will speak when the time of resurrection. And this is the time of resurrection because Kundalini resides in the sacrum, which is the Aquarius. And this is the age of the Aquarius; this is the age of the kundalini.
