You did a nice looking.I don’t know where they come from, they seem to just appear. They don’t appear to go anywhere, they just come and then go.
This is how we look at thoughts. Looking how they come and go, and observing the short gap between them. Noticing how the current thought is passing. And waiting for the next thought to come. It is just simple.
Keep looking at this as many times as you can during the day. What is the feeling that arises - disappointment, frustration, excitement, amazement, joy?I am NOT in control of the thoughts that appear.
Now let’s do some more investigation in thought and especially thought about “me, “I”, self.
Get a sheet of paper and draw a line that divides that sheet in half. Label one half 'self' and the other side 'other'. Sit down and start a timer for 5 minutes. Every time you have a thought make a mark on the sheet. If that thought is about the self put a mark on the self side, if it’s about something else, mark the other side. If a thought about food occurs due to feeling hungry, mark that on the self side. Any thought that refers back to a self should go on the self side. (I'm bored, I'm tired, is the door locked (my safety) that video was funny (I was amused), my back hurts, I am frightened)...
Take you time and let me know what you find.
Much love to you.
