I believe the answer would be how it is performed.
<span>Visualization
is when a person pictures images in one's brain depicting personal desires that
one would want to happen in reality. It has been proven to relax and refuel the
mind after a hard day's work. Visualization helps in lowering blood pressure and the level of stress
hormones in the blood. Quieting the mind and visualizing the exact details of
any stressful situation makes things manageable.<span>
<span>Aside
from relaxation, some people actually use this technique to achieve their own
personal or professional goals. Athletes commonly apply this in training where
they visualize every detail or possible outcome of their competition. Others
generally use this technique to deepen self-awareness where they can get touch
with their intuitions. </span></span></span>
