Dhyana is spoken of, and a few examples are given of what to meditate upon. Sit straight, and look at the tip of your nose. Later on we shall come to know how that concentrates the mind, how by controlling the two optic nerves one advances a long way towards the control of the arc of reaction, and so to the control of the will. Here are a few specimens of meditation. Imagine a lotus upon the top of the head, several inches up, with virtue as its centre, and knowledge as its stalk. The eight petals of the lotus are the eight powers of the Yogi. Inside, the stamens and pistils are renunciation. If the Yogi refuses the external powers he will come to salvation. So the eight petals of the lotus are the eight powers, but the internal stamens and pistils are extreme renunciation, the renunciation of all these powers. Inside of that lotus think of the Golden One, the Almighty, the Intangible, He whose name is Om, the Inexpressible, surrounded with effulgent light. Meditate on that. Another meditation is given. Think of a space in your heart, and in the midst of that space think that a flame is burning. Think of that flame as your own soul and inside the flame is another effulgent light, and that is the Soul of your soul, God. Meditate upon that in the heart. Chastity, non-injury, forgiving even the greatest enemy, truth, faith in the Lord, these are all different Vrittis.
