6.105

「又三因緣七種行故」等者，趣入、安住、攝受，名三因緣。正見、正思惟，名初趣入因緣；正語、業、命，名安住因緣；正精進、念，名攝受因緣。由此三因七道支故，令心內定，心正一緣。

Regarding 'Furthermore, because of three conditions and seven kinds of practices,' and so forth: entering, abiding, and sustaining are called the three conditions. Right view and right intention are called the conditions for initial entry; right speech, right action, and right livelihood are called the conditions for abiding; right effort and right mindfulness are called the conditions for sustaining. Due to these three conditions and seven path-factors, one causes the mind to become internally concentrated and the mind to be correctly focused on a single object.
