The Pungra Coach Library holds teaching videos and original tracks that are free to use when introducing Pungra informally or preparing a taster session. It's a good source for short clips to show people before their first session, since seeing the format is far more persuasive than describing it.
If you'd like a certified instructor to help with a taster session in your area, use the instructor directory to find someone nearby, or get in touch through the Pungra contact details if there's no instructor listed yet.
