Zen Buddhism
Zen in its own words
A special transmission outside the scriptures
Without reliance on words or letters
Directly pointing to the heart of humanity
Seeing into one's own nature.

Zen Buddhism
Zen Buddhism is a mixture of Indian Mahayana Buddhism and Taoism. It began in China, spread to Korea and Japan, and became very popular in the West from the mid 20th century.
The essence of Zen is attempting to understand the meaning of life directly, without being misled by logical thought or language.
Zen techniques are compatible with other faiths and are often used, for example, by Christians seeking a mystical understanding of their faith.
Zen often seems paradoxical - it requires an intense discipline which, when practised properly, results in total spontaneity and ultimate freedom. This natural spontaneity should not be confused with impulsiveness.
Zen - the word
'Zen' is the way the Chinese word Ch'an is pronounced in Japan. 'Ch'an' is the Chinese pronunciation of the Sanskrit word Dhyana, which means (more or less) meditation.
Zen - the essence and the difficulty
Christmas Humphreys, one of the leading pioneers in the history of Buddhism in Britain, wrote that "Zen is a subject extremely easy to misunderstand." He was right.
Zen is something a person does. It's not a concept that can be described in words. Despite that, words on this site will help you get some idea of what Zen is about. But remember, Zen does not depend on words - it has to be experienced in order to 'understand'.
Enlightenment is inside
The essence of Zen Buddhism is that all human beings are Buddha, and that all they have to do is to discover that truth for themselves.
All beings by nature are Buddhas,
as ice by nature is water.
Apart from water there is no ice;
apart from beings, no Buddhas. Hakuin Ekaku
Zen sends us looking inside us for enlightenment. There's no need to search outside ourselves for the answers; we can find the answers in the same place that we found the questions.
Human beings can't learn this truth by philosophising or rational thought, nor by studying scriptures, taking part in worship rites and rituals or many of the other things that people think religious people do.
The first step is to control our minds through meditation and other techniques that involve mind and body; to give up logical thinking and avoid getting trapped in a spider's web of words.
History
Zen Buddhism was brought to China by the Indian monk Bodhidharma in the 6th century CE. It was called Ch'an in China.
Zen's golden age began with the Sixth Patriarch, Hui-neng (638-713), and ended with the persecution of Buddhism in China in the middle of the 9th century CE. Most of those we think of today as the great Zen masters came from this period. Zen Buddhism survived the persecution though it was never the same again in China.
Zen spread to Korea in the 7th century CE and to Japan in the 12th century CE. It was popularised in the West by the Japanese scholar Daisetz Teitaro Suzuki (1870 - 1966); although it was found in the West before that.
