In this section there are links to Teisho by Dunedin Zen Group resident teacher Glenn Wallis Roshi.

A Teisho is a presentation of Dharma typically given during a Sesshin, or Zen intensive ‘retreat’. Because we use words to communicate ideas this is the form of the presentation, but beyond this Teisho is actual live presentation of Dharma, of actuality as it is. By nature Teisho is an oral presentation.

The Teisho offered here are transcriptions with a minimal re working for written form in an effort to retain original impact and presentational value. The way to read a Teisho is the way you listen to one. As if it solely for you and you alone. Which is actually, deeply, the case.
