By not stopping our thoughts and feelings in meditation,  we are paving the way for gentle ways of being with our experience. When thoughts are intentionally cut off, that is often an act of harming. If it is done aggressively, even with a miniscule amount of force, it supports and furthers the tendency to get rid of thoughts rather than the tendency to get to know them. Our ability to get to know our thoughts and feelings depends on our ability not to get rid of them. Holding our experience gently,  thoughts and feelings come and go  in their own time.
