Following his own enlightenment, Seongcheol practiced jangjwa buwa, long sitting without lying down, for eight years, remaining seated in meditation posture through the night rather than lying down to sleep, a documented ascetic discipline distinct from the doctrinal argument against Jinul's formula his first article covers. Accounts of the period describe him denying that he slept at all during those eight years, a documented physical austerity distinct from anything in the account of his philosophical dispute with the sudden and gradual formula.
Seongcheol also made himself deliberately difficult to reach. Visitors who wished an audience with him, however senior their own standing, were commonly required to perform three thousand prostrations before he would agree to meet them, a documented condition on access distinct from the intellectual content of the debate his first article recounts, and one that turned even the practical matter of seeking his advice into its own test of sincerity. The requirement became one of the most widely repeated details of his reputation within Korean Buddhism, cited by disciples and visitors alike as characteristic of the man well beyond his formal teaching.
That a teacher whose first article shows him overturning an eight centuries old doctrinal consensus through argument alone also held his own body to a physical discipline few other teachers of his rank attempted, and made even reaching him a matter of physical exertion rather than rank or credential, marks the eight years of jangjwa buwa and the three thousand bows as a documented case where Seongcheol's authority rested as much on visible practice as on the reasoning his first article traces.
