When you are feeling down do what your body is designed to do and walk.
A walking meditation is an opportunity to quiet the mind and experience sensory data. Start walking and place your feet firmly on the path from heel to toe and release your mind.
Breathe and feel the air move through your nose or mouth, feel your stomach move in and out with your diaphragm, feel the stretch and contraction of your muscles, the air softly gliding over your skin and the changing temperature of sun and shadow.
Let your eyes float over your surroundings , become lost in the droplets of dew on the grass, the shiny yellow gleam of the buttercup, the fluffy head of the clover and the closed up faces of the daisies waiting for the sun before they show their yellow centre. See the hues of blue and drifting white decorating the sky. Submerge your mind in the many shades of green.
Smell the morning fresh from night, smell the greenness of growth, abundance and renewal, smell the acrid exhaust of cars passing by, the dry smell of sun on concrete. Let the scents of your world entwine in your mind.
Listen to the busy chirping of birds greeting the day or the night; hear the rising sound of tyres on asphalt, the susurration of the wind and drifting in the musical sound of chimes.
Feel how your body engages with your world as all the sensory information is absorbed. Feel a quickness in the blood flowing through your body and feel a mind gently resting in a network of sensory data absorbing and filtering it through you as you become an intrinsic part of your environment.
