Those outlived relationships or experiences that are pretty much hindering your life path.
It takes a concerted effort to break those ties, but once its done it can prove to be a liberating experience.
We are not meant to stay in one place for too long. The same experiences over and over again will prove to be unhealthy and debilitating. All it takes is courage and gritty determination to break ties with the old, and permit new experiences to come into your life. Once the process commences, the benefits from the spring clean will soon be felt.
The process is best undertaken by focusing on where you wish to be at the end of it all; looking into the future and visualising the end result. Its best not trying to comprehend how you are going to get there. Let fate and universal forces do that bit ... just be aware that once the ball is rolling it will gather momentum, and life can never be the same again.
It is a growth, and cleansing process, to let this happen. The outlived things in your life --- whether it is a person, or a job, or a place, or a situation --- really need to be dispelled from your thought processes. Your perceptions of life will always be the same if nothing changes in your physical life. Once different stimuli start to appear in the life around you, then you will think differently.
A word of warning, not all of the changes will happen at once. You may well find a series of events like synchronicity happening, but they will cease once you get to a certain point; then commence in in a smaller or a larger degree at another point in your life further down the track. There are times when you will feel like you are in suspended animation when fate is manifesting the next stages on your behalf. The idea is to keep focused on the long term plan and let your thoughts think in that way.
