Knowledge of Vajrayana is intrinsic to human beings, in the sense that Vajrayana is our condition. It is the thread of continuity which runs through every aspect of what we are. In this sense Vajrayana may be invisible – but it is also sharply and poignantly perceptible. The Lama shows us the reality that Vajrayana is already there as the basic energy of our existence.p68, Entering the Heart of the Sun and Moon Ngakpa Chögyam and Khandro Déchen, Aro Books, 2009, ISBN 978-0-9653948-3-3
