Our meditation will become easier once we realize that we can say to our mind, “Peace, be still.” Some of us have undoubtedly seen pictures, statues, or figures of Lao-tzu sitting on a horse backwards, not facing the horse’s head but his tail. The meaning of this is that Lao-tzu, the mystic, the man of God, has control of his senses. He does not need to hold reins; he does not need to look where he is going. He is in control of his senses and can forget the human element of control. He is a master and, being a master, he does not have to observe material laws by facing forward, holding the reins, or kicking the horse in the sides. He sits there and contemplates.
There are no masters except those who are in control of mind and body. And if they do not have that control, they are not masters. You and I are masters only as we can demonstrate that the mind and the body are under our dominion.

‘This body does not constitute me: this is a body which is an instrument for my use. I am in the Father, and the Father is in me. I am subject unto the Father; I do His will. I do the will of no man; I obey the will of no man. I look not to “man, whose breath is in his nostrils.”
I look not to the favor of princes. I and the Father are one, and I am subject only unto my Father because I do the will of my Father. I turn within and receive instruction and light from the Father.’

Life becomes a matter of introspection and withinness, letting infinite God, good, infinite consciousness, pour Itself through us, as us, without our having to take conscious thought, but always being obedient to its leading. When the Master was on the ship in the midst of a storm and commanded the sea to be still, he was not addressing a storm external to him. The storm was within him. A storm is a mental illusion, a mirage. It is not externalized, and no one can command it to be still. But we can say to the mind that is entertaining an illusion, “Peace, be still. My peace give I unto thee.”
When you want to meditate, say to your mind: “Peace, be still. My peace give I unto thee. The Christ-peace give I unto thee. I bring to thee peace from my Father.” As you find your body becoming unruly, do not be afraid to address the body, although actually it should not be necessary because the body is mind formed and if the mind is brought into stillness, the body will be still, just as by bringing the mind into stillness, the storm subsided.
When you learn there is an I, let I address your mind:

‘Peace, be still. The peace of God be upon thee. I live by the grace of God. I live by God’s government, and so, mind, be still. Peace be unto thee. My peace give I unto thee.’

It will not be long before the mind settles down into peace, because you have asserted your God-given dominion over your mind, not over anyone else’s mind.
