19.189

於內心奢摩他中行正行如其主於能致財可委附者，依定起行行不傾動，如人置財可委附者，於增上慧法毘鉢舍那中行於正行如善巧者於諸巧事者，依善巧慧集起諸行，如善巧師集起巧中。

Where it says 'practicing correct practice in internal śamatha, like its owner regarding someone capable of bringing wealth and worthy of trust', one initiates practice based on concentration, and the practice is unshakeable, like a person entrusting wealth to someone worthy of trust. Where it says 'practicing correct practice in the higher wisdom of vipaśyanā of phenomena, like a craftsman regarding craftsmanship', one gathers and initiates practices based on skillful wisdom, just as a master artisan creates craftwork.
