Before we can control the mind we must study it. We have to seize this unstable mind and drag it from its wanderings and fix it on one idea. Over and over again this must be done. By power of will we must get hold of the mind and make it stop and reflect upon the glory of God.

The easiest way to get hold of the mind is to sit quiet and let it drift where it will for a while. Hold fast to the idea, "I am the witness watching my mind drifting. The mind is not I." Then see it think as if it were a thing entirely apart from yourself. Identify yourself with God, never with matter or with the mind.

Picture the mind as a calm lake stretched before you and the thoughts that come and go as bubbles rising and breaking on its surface. Make no effort to control the thoughts, but watch them and follow them in imagination as they float away. This will gradually lessen the circles. For the mind ranges over wide circles of thought and those circles widen out into ever-increasing circles, as in a pond when we throw a stone into it. We want to reverse the process and starting with a huge circle make it narrower until at last we can fix the mind on one point and make it stay there. Hold to the idea, "I am not the mind, I see that I am thinking, I am watching my mind act", and each day the identification of yourself with thought and feeling will grow less, until at last you can entirely separate yourself from the mind and actually know it to be apart from yourself.

When this is done, the mind is your servant to control as you will. The first stage of being a Yogi is to go beyond the senses. When the mind is conquered, he has reached the highest stage.

Live alone as much as possible. The seat should be of comfortable height; put first a grass mat, then a skin (fur), next a silken cover. It is better that the seat has no back and it must stand firm.

Thoughts being pictures, we should not create them. We have to exclude all thought from the mind and make it a blank; as fast as a thought comes we have to banish it. To be able to accomplish this, we must transcend matter and go beyond our body. The whole life of man is really an effort to do this.

Each soul has its own meaning: In our nature these two things are connected.

The highest ideal we have is God. Meditate on Him. We cannot know the Knower, but we are He.

Seeing evil, we are creating it. What we are, we see outside, for the world is our mirror. This little body is a little mirror we have created, but the whole universe is our body. We must think this all the time; then we shall know that we cannot die or hurt another, because he is our own. We are birthless and deathless and we ought only to love.

"This whole universe is my body; all health, all happiness is mine, because all is in the universe." Say, "I am the universe." We finally learn that all action is from us to the mirror.

Although we appear as little waves, the whole sea is at our back, and we are one with it. No wave can exist of itself.

Imagination properly employed is our greatest friend; it goes beyond reason and is the only light that takes us everywhere.

Inspiration is from within and we have to inspire ourselves by our own higher faculties.
