'Vipassana' is a meditation technique which takes time to learn. The courses are held regularly at the Blackheath centre. They run for 11 days, of which 10 days are held in silence. The 10 days consist of intense, unbroken meditation. This means you will be sitting in stillness for at least 10 hours a day. Most of this is conducted in the pleasant meditation hall. Men and women are separated. You can speak with the course organisers if you need something. This vow of silence strictly includes no touching and no eye contact with others.
