The Vajra Heart is the second book in the Guhyagarbha series of translations for restricted circulation.
The collection presented in Vajra Heart is meant for the beginner as well as the advanced practitioner. This collection lays out a graduated path that can be followed in the course of a day or a lifetime.
The skillful method of Tulku Urgyen Rinpoche's teaching is to never separate any practice or activity from the view of Dzogchen. Rinpoche himself especially wants to make people understand the importance of receiving the pointing out instruction and the necessity of requesting it from a qualified master.
— From the Preface
Note: "This book should only be read by or shared with Dharma students who have completed the preliminary practices and received the pointing-out transmission from a qualified master."
— H.H. Dilgo Khyentse Rinpoche
