For you, it’s more useful when you have thoughts, to look at the feeling associated with the thoughts. Also, don’t go too much into the feeling; and don’t name the feeling.
Just recognize that this thought and this feeling are associated, and this is just a feeling (yogi’s note: a feeling is known). What is it like? Don’t name it; just know it.
Know it’s changing; know what happens – the arising, getting more or less. That’s what you want to do; follow its trail.
