It took a long time for the analytical world to look at the importance of the way a baby is held, and yet when you come to think of it, this is of primary importance. The question of holding brings up the whole issue of human reliability.  

Winnicott

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 to get to know them.  Our ability to get to know our thoughts and feelings depends on our ability to stay with them,  and staying with them depends on our capacity not to get rid of them. Holding our experience gently, thoughts and feeling come and go in their own time.
