Patrul Rinpoche

In the Words of My Perfect Teacher (Kunzang Lama'i Shelung)

From the chapter, How to Follow a Spiritual Friend

The extraordinary teacher who gives the pith instructions
Has received empowerments, kept the samayas, and is peaceful;
Has mastered the meaning of the ground, path and result tantras;
Has all the signs of approach and accomplishment and is freed by realization;
Has limitless compassion and cares only for others;
Has few activites and is wholly preoccupied with Dharma;
Is weary of this world, and leads others to feel the same;
Is expert in methods and has the blessings of the lineage.
Follow such a teacher, and accomplishment comes swiftly.
