It is tradition to begin the Kuji meditations in the morning. I recommend following this because this is when the energies are the most fresh and potent, and also the rising sun is a symbol of invoking energies. However, if you have determined that you shall begin this practice, yet have awaken a bit late and have to get to work (or school), which has actually happened to me in the past, then do it when you get time. But do it that same day.
Now, after awakening it is preferred that you wash your hands and feet and rinse out your mouth, much like the muslims do before their prayers. Then walk outside, if you can, and face the North. Take in a deep breath, filling you belly with the air. Focus on all the tainted energy in your body. Exhale it all out of it, imagining that it is being carried by the breath out to infinity in the north, forever into eternity to dissipate into nothingness.
Turn to face the East and take 3 deep breaths through the mouth, inhaling all the fresh and new positive energies being brought into being by the morning sun. Feel it touch every part of your being, creating a feeling of warmth and healing everywhere it touches. And if it helps, imagine that it is a golden energy. The Prana of Yoga, the Chi of Chinese philosophy, the Ki of the Japanese arts. It enters you and becomes you.
Click your teeth together 36 times. Run to tip of the tongue along the outside of the teeth 9 times. Then do the same along the inside of the teeth. The saliva that remains, do not swallow it just yet. The energy you inhaled before, imagine that it is charging the saliva. In one large gulp, swallow it. Visualize a golden pearl of energy dropping downward. As it reaches the lowest point of the abdomen, it is warming and fills the entire body with life energy.
Now place your hands in the prayer pose as shown above (Kongo Gossho) and say the following Buddhist prayer:
"Deities of Heaven and Earth, grant the elimination of evil for longevity and peace. Hear and recieve this request for inspiration. May truth descend upon this seat. With utmost sincerity, as in ancient times, may virtuous benefit be gained from Heaven."
"Homage to Marishi-Ten, the main revered of the gathering worlds, show your shadow form and grant the armor of protection."
"ON A JI CHIYA YA HO RI SHI YA SOWAKA"
