I'm working my way towards the end of week 3. This is where we work on the 7 main chakras. I'm used to working with chakras in my work as a medium and so rather than do one each day, I did them all one after the other, each time. The first time I did this I experienced the most amazing strobing at the brow. I often get coloured blobs strobing when I do my normal meditation, but this was something else. This was bright white 'comets' with wavy tails that wiggled their way towards me at great speed, I just lay there and thought "wow". After about 20 seconds or so it went away but then a few minutes later it happened again briefly. I was amazing but since then I've not had it happen again. Does this mean I'm doing something wrong?
