The Heart Wisdom series aims to make the teachings of Ringu Tulku Rinpoche available to a wider audience, by bringing his oral teachings to the written page. In this volume, Ringu Tulku offers a commentary on the practice of Vajrasattva found in Brief Recitations for the Four Preliminary Practices by His Holiness the 17th Karmapa. Detailed descriptions of Refuge and Vajrasattva practices are given and the full root text is included for the reader's own practice.Ringu Tulku explains what purification really is - the quality particularly associated with Vajrasattva - and encourages us to explore this, through the formal meditation but also in our daily lives.'The essence of our mind is the vajra. Emptiness is the vajra. When we understand the way things really are, we become free from all fear and clinging. We understand how we are indestructible, because we are emptiness.'
