What energy are you still holding on to from your past? Are you carrying around old items, papers or pictures that remind you of bad memories? Are you holding on to things for a "rainy day"? All of these physical items are attached to your own emotional baggage. Until you look around and rid yourself of these items, you will not be able to move forward on a physical or emotional level.
What in your life would you like to manifest? Do you want to manifest a relationship? Find out what physical and emotional attachments to your last relationship keep you from moving forward. Do you want to manifest a new home? Go through old papers and photos and purge any attachments to old dwellings and old energy.
Only when you create an empty space both physically and emotionally, can you begin to fill it with the object you are working towards manifesting. Once you have purged the items and emotions related to your past experiences, only then can you open up a space to be filled with the new energy that you are welcoming in.
In order to manifest, first the thought must be there and then the Spirit world begins to move energy toward your desired outcome. But, if you are blocking it with emotional memories or physical items you have been unable to release, then this will slow or even stop the flow before your thought can become reality.
When you are unable to release things on a emotional or physical level, you put more blocks in the way of the fruition of your hopes, wishes and dreams. When manifesting, the energy must come through all of your bodies, spiritual (or etheric), mental, emotional and then physical in order to come into being.
Look around your home, your car, your computer and clear out the things that you no longer need or use or things that are attached to the energy of the past. Donate them to someone who can use them or dispose of them. You will feel lighter with each load that you dump and your energy will begin to change immediately.
