The following exercise is short but very powerful. Do it
regularly and you will definitely feel the difference.
This can be done anywhere except of course while
driving. It may be necessary for you to do this where
there are no distractions until your concentration and
focus improves.

Sit comfortably or lie down.(After some practice you
can do this while you are showering)

Close your eyes and take a few deep breaths, inhaling
through your nose and exhaling out of your mouth.

Visualize a golden cloud above your head.

See golden rain drops coming out of the cloud.

See these drops and feel them cleansing your Aura. 
 (The area around you, from your physical body out to
about three feet.)

See the golden drops penetrate your skin, in through all
parts of your body, all the way down to the cellular
level. Knowing that all aspects of you are being
cleansed. Feel the joy this exercise provides. See this
residue wash into the earth, knowing that as you
release these negative energies you are also providing
nourishment to the earth. See plants and flowers
growing and blooming all around you.  

Sit with this experience for awhile.

Take a couple breaths to complete.
