Zen is one of the key concepts in Buddhism , the essence of which lies in the mystical "contemplation" of the inner and outer worlds of the beholder. Contemplation, whose goal is to achieve enlightenment.
The Japanese word "Zen" goes back to the ancient Indian "dhyana", meaning "immersion, deep contemplation". The main aspiration of the followers of Zen Buddhism is "enlightenment", which, according to the Buddhist tradition, everyone is able to achieve through meditation and immersion "in oneself." In modern Western culture, the word "Zen" (in English is written Zen) means detachment from domestic trivia and immersion in spiritual practices.
