If you are aware of other thoughts entering your mind,

If you are aware of other thoughts entering your mind,
just let them go and bring your attention back to counting
and breathing. Continue doing this for a few minutes. (If
you practice this, you will begin to strengthen the
Diaphragmatic Muscle, and it will start to work
normally—leaving you with a nice relaxed feeling all the
time.)
Now move your attention to your feet. Try to really feel
your feet. See if you can feel each toe. Picture the base of
your feet and visualize roots growing slowly out through
your soles and down into the earth. The roots are growing
with quickening pace and are reaching deep into the soil of
the earth. You are now rooted firmly to the earth and feel
stable like a large oak or redwood tree.
Stay with this feeling of grounded safety and security
for a few moments. Once you have created a strong feeling
or impression of being grounded like a tree, visualize a
cloud of bright light forming way above you. A bolt of
lightning from the luminous cloud hits the crown of your
head, and that ignites a band of bright white light
descending slowly from your head all the way down your
body, over your legs, and out past your toes.
As the band of light passes over you, feel it clearing
your mental state. It is illuminating your mind and clearing
any disturbing or stressful thoughts that you may have been
thinking about. Repeat this image four or five times until
you feel a sense of clearing and release from any anxious
thinking.
In finishing, see yourself standing under a large,
luminescent waterfall. The water is radiant and bubbling
with vitality and life. As you stand under the waterfall, you
can feel the water run over every inch of your body,
soothing you and instilling within you a sense of deep calm.
