You are very clear about thoughts but there is still a point to explore.
1) Write down what you said without using "I" and "me" and let me know about sensations arising or whatever.I'm a bit caught in seeing this completely. If I see a negative thought and change it to a positive thought it seems to me that I am choosing that shift to a positive thought.
2) Look at what is going on : a negative thought is seen, right? Then a thought about shifting to a positive thought is seen, isn't the case?
Do you see clearly that a thought CANNOT BE known before it arises? Can we predict a thought before it arises, before it is noticed?
Do you see clearly that there is no you (me) in charge of thoughts, producing them or choosing them? That there is only the knowing (being aware of them). Anyway, if there is a me, which kind of me it is? Can you describe it?
Light (knowing, being aware) is like the sun. Sometimes the sky is clear with no clouds (thoughts). Sometimes the sky is cloudy. It does not mean that the sun disappeared. Light and clarity are here. There is knowing of thoughts. "Being lost in thoughts" means that the sun is lost in the clouds. Is it the case? When thoughts are overwhelming, just take a step back and stay as the light, the knowing (awareness). There is no need to "translate" negative thoughts to positive thoughts. The sun does not care about light clouds and heavy clouds, the sun is at a distance.
The same comments as above.The thought is not known before it arises yet is known as it arises from my choice to shift to a positive thought. What am I missing here? I want to see this.
I hope that all what is said here will help you to clarify from doubt. Anyway, I am with you till you see clearly and certainty that there is no separate self in any shape or form.
Best wishes
