Dilgo Khyentse Rinpoche explains the general foundational practices according to the Nyingma tradition, from the teachings of Jamyang Khyentse Wangpo. These preliminary practices include taking refuge, generating bodhicitta, Vajrasattva purification, mandala offering and guru yoga. Clear, direct and personal, these instructions illuminate the heart of Vajrayana practice. Included here are the Tibetan text as well as the mantras and prayers commonly recited in conjuction with this practice.
"The vow to perfect oneself in order to perfect others is called the thought of elightenment, or bodhichitta. This implies that every single action, word or thought, even the most trivial, is dedicated to the good of all beings. To accomplish the good of others, we must first perfect ourselves, by purifying and transforming our minds. This is the aim of what we call the preliminary practices, which establish the foundations of all spiritual progress." ~ Dilgo Khyentse Rinpoche.
