勸修加行，云遍於一切正加行中乃至如前應知者，景云：勸初修者遍於九種正加行中，應修如此阿那波那止品所攝無倒加行，正加行中所餘八種如前所明。

Regarding exhorting the cultivation of preparation, the text says: "universally throughout all proper preparations... up to, should be known as before." Jing says: it exhorts the beginner that throughout the nine kinds of proper preparation, one should cultivate such non-erroneous preparation subsumed under the category of calm (śamatha) of ānāpāna; the remaining eight kinds among the proper preparations are as clarified before.
