In one of Miles O'Brien's memories of being in an Argrathi prison, he was taught by Ee'char how to draw geometric patterns called Eseekas. In explaining how to draw these patterns, Eechar demonstrated to O'Brien that they "[s]tart by drawing a circle" [...] then "gaze into the circle" and "relax your mind." Eechar continued, "[i]magine that the circle encompasses your whole existence. Let it become a part of you. Now without thinking, allow your hand to make a mark inside the circle. Now expand on the mark. Let it grow organically until it becomes a pattern." ()
