"..... a short meditation or pious thought for 30 occasions or moments during the day, from the early morning to the late evening (see ’table of contents’). "The author teaches how during all daily activities, even the most simple ones, one can elevate one’s soul to God, while observing the infinite perfections of God in material objects and thanking him for his blessings and accepting the hardships of life with resignation. The style of this text is simple and the thoughts are pious" (Pfister, in translation). The text opens (f. 1a3) with referring to an admonition expressed by Jesus: 吾主耶穌在世訓十二宗徒曰 爾當恆求天主而無倦 (cf. Luke 18:1, “And he spoke a parable unto them to this end, that men ought always to pray, and not to faint”)" --Cf. Ad Dudink & Nicolas Standaert, Chinese Christian Texts Database (CCT-Database).
