Item 23 : Noe - heo(雷虛,뇌허)... Hollow Thunder(An Empty Thunderous Sound)... Item 27.
● Noe - heo(雷虛,뇌허) means that a mind perfected in sincerity becomes
bound or entangled by what the ears hear.
● When true sincerity manifests outwardly,
it may display itself with a sound as grand as thunder,
however, if one remains utterly empty and hollow Within,
they hear absolutely nothing (remaining undisturbed by external noise or praise).
[Original Text]
■ 雷虛者는 誠心이 纏于耳聞하야 (뇌허자는 성심이 전우이문하야)
Noe - heo means that a sincere mind becomes entangled and bound
by the hearings of the ear.
■ 誠發之時에 以雷聲之大로 自虛而不聞也라. (성발지시에 이뇌성지대로 자허이불문야라.)
When sincerity bursts forth,
it does so with the greatness of a thunderous roar,
yet one makes oneself empty within and does not hear it.
