Dharma Talks & Recordings
In some Zen traditions a Dharma talk may be referred to as a teisho. However, according to Taizan Maezumi and Bernard Glassman, a teisho is “a formal commentary by a Zen master on a koan or Zen text. In its strictest sense, teisho is non-dualistic and is thus distinguished from a Dharma talk, which is a lecture on a Buddhist topic.” In this sense, a teisho is thus a formal Dharma talk.
A Dharma talk must always be appropriate in two ways: it must accord perfectly with the spirit of the Dharma and it must also respond perfectly to the situation in which it is given. If it only corresponds perfectly with the teachings but does not meet the needs of the listeners, it’s not a good Dharma talk; it’s not appropriate.
