I had a Zen teacher in Beijing that explained to me that Zen is a traditional Chinese method about reaching wisdom and attainment of enlightenment, through meditation and Yoga body relaxation technique (a sub branch of Zen).

There are several ways of practising Zen, notably meditation in room blessed by a Zen master (my teacher was one and would give us a cheap price for rent) or by listening to the music to get a passive gain to Zen. And I like the music because it really helps. I bought some CDs from him, but i secretly thought it was a bit too... rushy. So I went to go look for moar traditional Chinese Zen music, and thanks to answers.echinacities.com, i found it!

Zen is a Japanese word and is similar to the practice of Taoism

i guess its sth related to TCM

Zen is a translation into Japanese of the Chinese ch'an, which itself is a translation from the Sanskrit dhyana (Pali: jhana), and is normally translated into English as 'meditation'. Although, this is a little incorrect as the pali for meditation is actually bhavana, literally meaning 'to become familiar'. The practice of seated meditation in Japanese Zen Buddhism is called zazen. As such, Zen is a tradition within Buddhism that names itself after its own fundamental practice.
