I just did a short 11-minute meditation at work , just staying aware of thoughts , emotions and sensations , trying to relax my abdomen.
There was heat in the abdomen , moving around. I notice this during the day also.
After I finished I decided to do an additional session. The 3rd eye got very active and there were sensations near my ears , as if someone was lightly touching that area. Again , there was heat in the abdomen.
