摩訶止觀 9.77

9.77

勝知見者：此心勝色，不為色所縛，心能轉色，故言「勝知」也；勝見者，淨不淨等皆於己心自在，觀解成就，故言「勝見」也。此兩，二禪攝。若勝處成時，身尚不惜，況財物、他身耶？上古賢人推位讓國、還牛洗耳，皆是昔生經修此觀，自然成性，無復愛染。不得此意，貪之至死，何能忽榮棄位耶？

Regarding 'superior knowledge and vision': this mind surpasses form and is not bound by form; because the mind can transform form, it is called 'superior knowledge.' As for 'superior vision': pure, impure, and the like are all under the mastery of one's own mind, and the contemplative understanding is perfected, hence it is called 'superior vision.' These two are subsumed under the second dhyāna. When the bases of mastery are accomplished, one does not even begrudge one's own body, let alone material possessions or the bodies of others. When ancient worthies abdicated their thrones, ceded their kingdoms, returned oxen, or washed their ears, it was all because they had practiced this contemplation in past lives; it naturally became their innate disposition, free of all craving and defilement. Without grasping this meaning, people are greedy unto death; how could they dismiss glory and relinquish their stations?
