Some say that if he cannot fall into sleep because of meditating on the Throat Center, he should concentrate on the forehead, visualizing a white Thig-le there. This is very erroneous, because the forehead is a place that, if concentrated upon, causes dreams to arise, (puts consciousness in operation in opposition to the tendency to sleep). This foolish statement is akin to saying that concentration upon the Sleeping Center will make one awake. If he concentrates on the Throat Center at dawn and twilight for a long period and still cannot hold the dream, he must be a person who requires a sound, heavy sleep. For him, meditating on the Eyebrow Center will help. If by doing this, the sleep then becomes too light and he is liable to awake, or he can not fall into sleep at all, he should visualize a Thig-le within the reproductive organ and also repeatedly strengthen his desire for recognizing the dream during the daytime as mentioned before. Before sleep, he should visualize a black in the center of the organ and practice the breathing exercise twenty-one times. Thus the destructive thoughts will be halted, and he can fall into sleep more easily. One should know that meditating on that organ is a cure for light sleep.

If through the practice [of meditating on the frontal sinus center] one still cannot subdue or overcome heavy sleep, one may follow such instructions as meditating on the month and year (visualizing the moon and sun). If by doing so, the yogi still cannot practice the Dream Yoga, he should know that only through the power of the (Wisdom)-Prana produced by the arising of the Innate Born Wisdom through the process of gathering, entering, and dissolving in the Central Channel of the Heat Yoga practice, one is able to hold a dream properly. Through the practice of intensive intention, no matter how hard one tries, he may still not be able to practice properly. Therefore, he should work hard on the superb Heat Yoga and try to lead the Pranas into the Central Channel. This is the primary practice, others being secondary.
