Cutting the Roots--From His Holiness the Dalai Lama

...the Mother Tantra chod emphasizes the importance of abiding in the natural state and understanding the illusory nature of things and oneself.

...Chod cuts the root of that illusion by eliminating the fear that attaches one to one's body after mistaking the body for oneself. By focusing on frightening objects, confronting them, cornering them, and being comfortable in or with them, fear leads to liberation from deluded awareness. It also brings, as a secondary benefit, the ability to repel physical and mental illnesses and energetic disturbances by meditating on what and who is being frightened by them. Being able to sustain that comprehension of the illusory nature of phenomena (including oneself) as one's view helps one recognize one's accomplishments in meditation, conduct, and result. This protects one from returning to the usual delusion and establishes instead a clear awareness (rigpa).
