We are often using tools to look inside and probe ourselves.
Here are a few things we can do to notice things about ourselves without leaning on tools.
1. Take a reflective surface from water to a mirror and look at your eyes. Breathe and listen to your pulse until you see your pulse in your eyes as well.
2. Balance a glass of liquid on the palm of your hand and allow the movement to calm. Breathe and note the vibration of your pulse through the liquid and use a simple breath hold drill to see it quicken as your body adjust to less oxygen.
3. Close your eyes and stand on one foot. Start moving your eyes up and down and side to side and finish with moving your eyes in circles. Notice how your foot automatically adjust to the changing point of focus and enjoy how responsive you really are to your simple wishes.
It is hard to be angry when you can pay attention.
The reason is you see no reason to be angry when you can do and think instead of living just on the inside.
