So, in that part of the exercise, when we let go completely, we are essentially dropping the filter, maybe for the very first time. This is why the dream world (where are thoughts generally go unfiltered) often appears so bizarre when we awake in the morning. Generally speaking, as humans, we tend to filter most of our thoughts.
In fact I would even say it is something good, something positive. Finally, coming back to your very first question, this is nothing to worry about at all. Instead, simply acknowledging the feeling, recognizing it is part of being human and understanding that all human beings experience something similar-even if it sometimes feels we are the only one. Mindfulness is about observing thoughts and feelings without judgment or criticism. Sure, we may not like the fact that we get anxious once in a while, but by adding anger and frustration into the mix, we are really just pouring petrol on the fire. This is very natural, but it’s worth considering how much you entertain the idea afterward. The next thing is the sense of anger you experienced. Sometimes the movement is very strong, at other times it is a little more subtle, but it is always there. An easy way to discover this movement is to place your hand on your stomach, diaphragm or chest and observe the movement as the body inhales and exhales. By this, I mean the movement of the body. So, as the body breathes it creates a rising and falling sensation. Of course, I’d be very happy to share a few thoughts.
