Breath Meditation
Breath meditation is the basic meditation behind all others, and so can be considered the most powerful. Even trances can be truncated in time through its use. Breath meditation is the oldest of all meditations; the first and biggest discovery of mankind. Likely developed by an ancient archetypal "Sith" who was later killed, and that art perverted into the archetypical "Jedi" orders, like the Shamans or the Samurai. There are two main types, both of which are Taoist:
Type One: Counted Breaths -Sit "Indian style", with your legs crossed under you. Then rest your arms on your legs. Now, close your eyes This is called the Six Point Position, as seen below.
-Now, breathe in, and count silently in your head, "In 1." -Breathe out, and count silently, "Out 1." -Repeat this until you reach the "Out 10." Then, count, still silently, "In 20." And continue to count by tens until "Out 100." -Now, count silently by hundreds to 1,000. Then, start all over. Continue to do this until you have attained a calmed, thoughtless, peaceful state of mind. Should thoughts or images pop up in your head while counting, simply ignore them and they will go as quickly as they came.
Type Two: Nasal Sensation -Sit in the six-point position. -Breathe in through your nose, noticing the sensation of air moving in through your nostrils. -Breathe out, once again noticing the sensation. Focus on nothing else, and continue this slow, steady breathing until calm or when desired.
These meditations are the base of all others. However, there is another basic type, developed by Lord Draconious, that should be known.
Type Three: Draconian Trance Meditation -Sit in the six-point position; or lay down... just don't fall asleep. Choose a quiet place. -Now, notice a steady sound; perhaps it's your heart or breathing, or maybe it's your watch. -Choose one of these steady rhythmic sounds, and focus on it. -The sound will become very loud. Hold your breath for periods of times, but do not hold it to the point of discomfort. -The deeper trance you are in, the longer your breath can be held. The longer you meditate this way the better.
