Do you think the poet advocates total inactivity and death?

The poet doesn't want that we should confuse stillness with total inactivity. That would amount to death but he does advise that we introspect deeply and not indulge in an activity that is mindless and thus potentially destructive for human beings. We should not be always moving for a while we should take some rest. A long silence can soothe the feelings and helps in removing the sadness and turmoil.
