No matter what country we live in, or what religion we believe in, or what work we do, the ancient wisdom of the Buddha can lead us to greater success, and higher happiness.

Door to the Diamond Way was written by Tsongkapa (1357-1419), the famous teacher of the first Dalai Lama. In 1402 he climbed atop a mountain called the Lion Crag, far above an ancient Tibetan monastery. Here he fell into a deep vision where he sat among the greatest teachers of two thousand years, immersed directly in the nectar of their wisdom. When he finally came out of his vision, Tsongkapa wrote a song to his teachers called The Source of All My Good. These verses are themselves an exquisite guide to inner and outer personal success. By tradition, they are used to prepare a disciple for the quest to make direct contact with angelic beings--a journey which is itself called "The Diamond Way."

The work has been translated by Geshe Lobsang Tharchin, one of the greatest lamas of modern times, along with Geshe Michael Roach, author of The Diamond Cutter.
