Persist, Endure, Follow, Watch
To be recognized and accepted by the peregrine you must wear the same clothes, travel by the same way, perform actions in the same order. Like all birds, it fears the unpredictable. Enter and leave the same fields at the same time each day, sooth the hawk from its wildness by a ritual of behavior as invariable as its own. Hood the glare of the eyes, hide the white tremor of the hands, shade the stark reflecting face, assume the stillness of a tree. A peregrine fears nothing he can see clearly and far off. Approach him across open ground with a steady unfaltering movement. Let your shape grow in size but do not alter its outline. Never hide yourself unless concealment is complete. Be alone. Shun the furtive oddity of man, cringe from the hostile eyes of farms. Learn to fear. To share fear is the greatest bond of all. The hunter must become the thing he hunts. What is, is now, must have the quivering intensity of an arrow thudding into a tree. Yesterday is dim and monochrome. A week ago you were not born. Persist, endure, follow, watch.
