An amazingly effective way to improve the clarity and control of your visualizations is to get into a relaxed of state of mind.
Once you are relaxed, make yourself comfortable physically and take a few deep breaths. If you are at home or in the office, find a nice, quiet spot where you can do this simple exercise.
When you are ready, visualize a relaxing scene such as strolling along the beach as the sun sets over the horizon. Make this image clearer and the colors more vibrant and vivid. Next imagine a funny or even bizarre scene with the characters who populate your beach. It could be a naughty child playing a prank on his parents who are sunbathing or a pet dog that has found a giant bone in the sand! Let your imagination go wild and let it paint all kinds of creative scenes in your mind. Make a mental note of your experience – what did you see, hear or feel?
Play around with this creative exercise until you feel refreshed, enlightened and entertained.
