1.64

答：「彼文先於根塵體其本寂，作功不已，知滅對遺，靈知一念方得現前。故知彼之一念，全由妙止所顯。不爾，何故五念息已一念現前？秖如五念何由得息，那得將彼相應一念類今剎那念邪？況奢摩他別用妙止安心，毘鉢舍那別用妙觀安心，優畢叉方乃總用止觀，故出觀體中一念，正是今之陰識一念也。何者？彼文序中先會定慧同宗，法爾中乃云故即心為道，可謂尋流得源矣。故出觀體云，秖知一念即空不空、非空非不空。言秖知者，乃即體（止也）了（觀也）理，今剎那是三諦理，不須專亡根境顯其靈知，亦不須深推緣生求其空寂，故云秖知，此乃即心為道也。若奢摩他觀成，顯出自性一念，何用更修三觀？」

Answer: "That text first realizes the fundamental stillness in the sense faculties and objects; after sustained effort, when awareness of extinction is forgotten in confrontation, the single thought-moment of luminous awareness finally becomes manifest. Thus we know that that single thought-moment is entirely revealed through wondrous cessation. Otherwise, why would the single thought-moment become manifest only after the five thoughts have ceased? Just consider how the five thoughts could cease; how can that corresponding single thought-moment be likened to the kṣaṇa thought-moment here? Moreover, śamatha separately uses wondrous cessation to settle the mind, vipaśyanā separately uses wondrous contemplation to settle the mind, and only upekṣā combines cessation and contemplation as a whole; therefore, the single thought-moment in the section identifying the contemplation essence is precisely the single thought-moment of consciousness of the skandhas here. Why? In the preface of that text, it first harmonizes concentration and wisdom as having the same source, and in the spontaneous nature [section] it says: 'Therefore, identical with mind is the Way'—this may be called tracing the stream to find its source. Therefore, identifying the contemplation essence, it says: 'Only know that a single thought-moment is empty and not empty, neither empty nor not empty.' Saying 'only know' means directly realizing (which is cessation) and comprehending (which is contemplation) principle. The present kṣaṇa is the principle of the three truths; there is no need exclusively to obliterate sense faculties and objects to reveal its luminous awareness, nor is there any need deeply to investigate condition-arising to seek its empty stillness; hence it says 'only know'—this is 'identical with mind is the Way'. If, upon completing the contemplation of śamatha, the single thought-moment of self-nature is revealed, what need would there be to cultivate the three contemplations further?"
