Katsudo!

"If you want to realize your own Mind, you must first of all look into the source from which thoughts flow. Sleeping and working, standing and sitting, profoundly ask yourself, "What is my own Mind?" with an intense yearning to resolve this question. This is called ""training"" or "practice" or "desire for truth" or "thirst for realization." What is termed Zazen is no more than looking into one's own Mind."
