A Dharma Protector is a Buddha appearing in a protecting aspect, whose main functions are to avert inner and outer obstacles that prevent practitioners from gaining spiritual realizations, and to arrange all the necessary conditions for their spiritual development.

The Dharma Protector Dorje Shugden is an emanation of the Wisdom Buddha Manjushri, who always helps, guides and protects sincere practitioners by granting blessings, increasing their wisdom and fulfilling their virtuous wishes. See the book Heart Jewel for more information, and the sadhanas Heart Jewel, Wishfulfilling Jewel and Melodious Drum and the CDs Kadampa Prayers, Songs from the Joyful Land and Songs of the Great Protector.
