I Want To Learn More About Zen Buddhism?

As you know, the Zen tradition is one of several Buddhist traditions that have come from Asia to the West. Zen arose in China around 600 CE through the merger of certain Indian Buddhist traditions with existing Chinese Taoist traditions.
From China, the Zen tradition spread into Vietnam, Korea, and Japan. In the last 50 years, Zen teachers from each of these countries have established centers in North America, Europe, and elsewhere. While there are differences in form and emphasis among these traditions, the “bone” of the teaching remains the same.
Zen training takes several forms. Practitioners sit in meditation, of course (“zen” means ‘meditation’); however, Zen also employs walking meditation, chanting, bowing, work practice, koans and other forms to train students.
Sitting meditation cultivates a strong center, so we can remain stable as outside circumstances change (as they always do, non-stop).
Chanting practice opens up our inherent compassion, so that we naturally act in ways that benefit others.
Bowing practice helps us let go of our habitual ways of functioning.
Koans (Chinese: kung-ans) are short, frequently puzzling stories that help us develop genuine wisdom.
As stability, compassion, and wisdom grow, then our life naturally benefits all beings. We can act with generosity and creativity in response to each unique moment. This is true liberation.
The first link below will help you find the Zen center nearest you. Zen students benefit greatly from regular encounters with Zen teachers or masters. Teachers serve as guides along the path.
There are two modern classics on Zen. These books are quite different from each other and together will give you a real taste of the tradition. (Links below.)
“Zen Mind, Beginner’s Mind” by Shunryu Suzuki Roshi
“Dropping Ashes on the Buddha” by Zen Master Seung Sahn

You might also want to see if there are any temples or practitioners located near you. It works best if you learn from a teacher, rather than only from texts. (The texts are important too, though.)
