Have you ever had samadhi experience? Could you share what was it like? Several days ago I had a strange experience during dharana-concentration. First couple of minutes I tried to concentrate on the point between my eyebrows. Then, it became impossible. My imagination ceased to work properly. I couldn't visualise anything: not my surroundings, not my body, nothing. I could see nothing but strange and unidentified lines and figures. To visualise anything became impossible. My inner dialogue continued, but I still couldn't see anything on my mental screen. I wonder what was it.
