Entering The Great Expanse is Tulku Sherdor's most important and timely book, the fruition of 40 years in the dharma. It explains, lucidly and precisely, and with doses of bracing humor, the deep meaning and vast benefits of the preliminary practices of Tibetan Buddhism, based on the Longchen Nyingtig (Heart Essence of The Great Expanse) tradition. It is a companion guide to the practice text, An Excellent Path to Omniscience. Morever, this work explains to the Western audience, based on a lifetime of experience, how to study and practice dharma correctly, in order to obtain genuine experience and realization. Using the practice of ngondro (the preliminaries) as a framework, this book explains the purpose, layers of meaning, and benefits of every level of dharma practice, including the highest levels of Vajrayana and Dzogchen. The instructions and explanations are the teachings of past lineage masters, but spoken to be heard by dharma students today. The oral instructions offered here are applicable broadly to every lineage of ngondro. The chapters on Bodhicitta, Vajrasattva, and Guru Yoga, in particular, are must-reads for everyone.
