But i learned a valuable lesson while getting these quick tutorials during a meditation circle. And that lesson was my mind does not allow me to meditate.
The example was, we all sat in a circle and everyone focused on the same thing, we focused on the circle of people and we envisioned us going higher in the sky to see a UFO and bring it to our sight, during this session i could start to see what i called "Auras" or "spiritual light" of everyone in the circle, just imagine a dark room with faintly visible lights forming a circle, and as i focused on us and tried to enlighten the picture i would get a bright flash of light through my vision, it looked like a streak of insanely bright light and it would throw off my concentration. I would shrug it off and try again, and as normal i would start seeing everyone's light and then BAM then dash of light happened again!
The person guiding us had no explanation to it besides my mind does not want me to be doing the meditation and is stopping me, or perhaps something else was keeping me from focusing so hard?
It is difficult for me to say because I was not there in person ( or spirit !

) .
But YES that sounds accurate . Something else , maybe it is a possibillity that must not be taken out of account .
Personally , let me try to put to you in layman's terms :
You were not sufficiently relaxed .
I do advanced dog training as well , I tell my rookies : to reach a state of UTTER calmness before training .
If not the dogs sense it and act accordingly .
Try it and let me know if it helps .
Also don't bring your concentration into "sharp" focus , what happens then it is pulled out of focus . Think of the sights of a gun . All three must be used as unit and not only one becase then your aim will be off .
