The individual that is stuck in that ever circling reality is unaware that all of these sparkles are around them than and that the change they keep asking to have is right there. This is the difference in vibration. When someone is at a particular vibration unless you make a conscious choice to clear out or to open up or to become in alignment with the higher vibration you are unaware that it is going on.
The things that might keep people in that endless cycle are lower vibrations and their ego, in most cases. Well, in all cases it is a lower vibration and in many, many cases it is your ego that is keeping you in that pattern frequently through the self talk or your belief systems or howsoever that relationship is between you as source and you as the human in this life.
