If we aren't our thoughts, what are we?

baiselmareo6 thought this was worth mentioning said

I recently read the free tad/meditationSHIFT guide, and one of the core components that it pushes is the idea that our thoughts are simply a facet of what we experience in our lives - that we should not be controlled by our thoughts because our thoughts are not us.

This is absolutely helping me to deal with my incessant thoughts, but if I’m not my thoughts, then what am I identified by?
