the other morning i became conscious,and in my mind,i heard myself humming a single monotone note.then i felt a tiny point of vibration begin in my heart chakra.i realised that the humming was causing it,so did a test-stopped humming(i'm not sure if it was a dream hum or if i was actually/physically humming)and a few seconds later the vibration stopped.at this point i became more awake,and tried again-humming,for real,sure enough the vibration started again,only stopping a few seconds after i stop humming.i then remembered the John Selby book i read recently,telling of the different sounds to chant to stimulate each chakra,so i started going thru the different tones,soon i had a tiny vibration in throat down to sub-navel charkras simultaneously!
the vibrations seemed to extend from the centre of the chakras,straight out to a point about 15 cms outside my physical body.

tres cool.
