The root texts of Longchen Nyingthig contain a text for Chod practice. The text is part of the root transmission of the Longchen Nyingthig dharma that Jigmey Lingpa received as mind treasure from Longchenpa. The text includes both an explanation of the practice and a liturgy for doing it. The text is popularly known by its Tibetan name "khadro gayjang", or "Sound of Dakini Laughter". This book contains a fresh translation of the liturgy, one that corrects the many mistakes, omissions, and un-necessary additions found in most translations available at the moment, and especially in the ones that are available free on the internet. The translation was intended to be used as a practice text, and the rhythms and poetry of the Tibetan original have been retained as far as possible. The Tibetan text assumes a high level of understanding of the system and its terminology. Therefore, several Tibetan commentaries have been written to explain it. The most popular one is by Dza Patrul and is called Profound Foremost Instructions for the Chod Practice Sound of Dakini Laughter. This commentary explains the details of all the visualizations involved in the practice and makes some very important comments about the right and wrong way to practice Chod. Amongst Tibetans, it is regarded as the best companion to Jigmey Lingpa"s text. Therefore, the author has translated it, included notes as necessary to clarify it, and included it in the book. Furthermore, new editions of both Tibetan texts have been made and included. These new editions of the Tibetan texts carefully correct mistakes found in the main Tibetan editions that are available at the moment and especially in the copies of Jigmey Lingpa"s text that are floating around on the internet.
