Protocol by Somadatta, 1982
Observation of three tunnels at once
"Exercise: imagining a rotating Ajna Chakra.
During the chakra exercise, several swirls formed, just like the ones that come before tunnels. They were coming from my thoracic area. This process was not synchronous, but with a little temporal difference. Finally there were three tunnels in front of me, with their ‘entrances’ very close together. I could see these openings very well. One of these tunnels was rather uninviting, so that I closed it and then observed the others for a while."
