In my experience usually such advices like feeling emotions rather then intellectualising them come from people who simply incapable of intellectualising them.
As I mentionned in another comment here, in my case, I used to intellectualize too much. Actually, intellectuallizing is the only way to do anything I knew for a long time: even when starting a new sport, I would start with a book or a series of videos about the theory and biomechanics of the sport.
For me, actually allowing me to feel without necessarily having a fixed interpretation, allowing a multiplicity of meanings, is what really unstuck things. Which does not mean that I do not interpret or use concepts, just that I do not reify them anymore.
