When we are meditating in a haunted graveyard, or even in our rooms, frightening external and internal appearances may arise during Chöd practice. If this happens, check the two 'superstitions'—the external, frightening appearance, and the internal appearance of the inherently existent 'I' that is frightened. Do they exist from their own sides? With determination, check for the 'I' that experiences fear, whether of a sight or a sound. Recalling that our purpose is to compassionately sacrifice ourselves to the spirits, and remembering emptiness of the three spheres of giving, we mix our minds with space and visualize the spirits consuming our bodies as well as our sense of an inherently existent self. After the spirits have eaten the body, again investigate the two superstitions. It is by checking for the independent 'I' that we come to realize emptiness.
