摩訶止觀 4.39

4.39

又「誦」者，背文闇持也。今觀心亦爾，三觀之名詮三諦理，即是其文。知名非名，研心諦理；觀法相續，常自現前，不生妄念，名之為「誦」。如此誦者，遍法界誦，非止八十誦也。

Furthermore, "recitation" means memorising and reciting by heart. Now contemplating the mind is also like this: the names of the three contemplations express the principle of the three truths, which is precisely their text. Knowing that names are non-names, one investigates the principle of truth with the mind; the contemplative method is continuous, constantly presenting itself naturally without generating false thoughts, which is called "recitation." Such recitation recites throughout the dharmadhātu, not stopping at eighty recitations.
