The further away seems your goal, the further within must you go. Each time you get to zero, become more focused than ever and make a shift into brighter light, or a more subtle dimension of mental stillness. In other words, when you feel that the mind is about to wander off, use the next number to replace the random thought that you were about to have. Drawing up energy is the gentle path of integrating wisdom as you gather your power. This is opposite to methods which forcefully raise the kundalini without concern for emotional and mental integration.
Wizards are out of their minds.
The Bhagavad Gita says that it is easier to control the wind than to control the mind. In this technique you discover some of the benefits of mantra meditation. When you find yourself daydreaming, begin again at zero. See how high you can count without leaving the third eye. If your mind is very scattered, it may take you fifteen minutes before you can even begin to count.
