Simultaneously concentrate your will on the medulla and the point between the eyebrows. Repeat the following affirmation, first loudly and then gradually in whispers, and finally silently:

I will my life-force to charge
With Godly will I will it charge
Through my nerves and
muscles all
My tissues, limbs and all,
With vibrant tingling fire
With burning joyous power
In blood and glands
By sovereign command
I bid you flow
By my command
I bid you glow
By my command
I bid you glow.
