Kyabje Tulku Urgyen Rinpoche's impeccable qualities were evident to all who met him and received pith instructions and empowerments from him. His teachings on mind nature and the path of the Great Perfection were unparalleled. He had confidence and utterly pure trust based on the personal, direct understanding that Buddha Nature really is present in every sentient being. Just like oil is present in each and every sesame seed, any sentient being can realize the awakened state and thus has the basis for enlightenment.

The pith instructions in Vajra Heart Revisited are concise, brilliant expositions on the path of Trekcho, starting with the ground, the preliminaries, shamatha, and viphashyana, Three Vital Words, up to and including teachings on guru yoga, and bardo. They are extremely clear explanations on all aspect of practice that the Dzogchen yogi can use as a manual of guidance and inspiration. They include key topics such as differentiating mind and awareness and threefold sky practice, among others. It is all that is necessary to attain full mastery and realization.
