Zazen Meditation

Zazen is a unique form of meditation that functions centrally in Zen Buddhism. So central in fact that Zen Buddhists are generally known as the "meditation Buddhists". Its goals are to calm the body and mind, and experience insight into the nature of existence and thereby gain enlightenment, known as "Satori". One might also say that Zazen is the study of the self.
Zazen meditation is performed seated with legs and hands folded and an erect but settled spine. The legs are folded into standard sitting styles. The hands are folded together into a simple mudra over the belly. One breathes from the "hara", the center of gravity in the belly, with eyelids half-lowered. The reason practitioners' eyes are neither fully open nor shut is so that one is not distracted by outside objects but at the same time is kept awake. Samurai warriors loved Zen culture.
