How do I study Zen?
Zen is primarily a matter of practice, not study, so you should try and find a group with whom you can sit regularly. The Buddhist Society in London maintains a list. Once you encounter a group, trust your instincts. If it feels right for you, stick with it, otherwise try somewhere else. No one owns Zen and be suspicious of those who purport to. If there is no group nearby, try and attend sesshins (periods of intense practice, usually for at least a weekend), make contact with a teacher and sit regularly at home.
Of course, because of technology, you can practice with a Group wherever you are. The Glasgow Zen Group offer the option of online sitting with us, which has been widely taken up.
