The Three Principal Aspects of the Path is a seminal text by Je Tsongkhapa that describes the three principal aspects of the path—the intention to be free (renunciation), the mind of enlightenment (bodhicitta), and the right view of the wisdom realizing emptiness—how to cultivate them, and how to know when you have realized them. This small text contains the essence of the entire teaching of Lord Buddha.
Lama Yeshe said, "In Tibetan, we call this text Lam tso nam sum. Historically, this book derives from Je Tsongkhapa's direct, visual communication with Lord Manjushri. Manjushri gave him this teaching and then Lama Je Tsongkhapa gave it to his disciples."
Translated by Lama Zopa Rinpoche.
