就釋初句中，云若愚其因，位果善巧者，十八界門正取十八界種子，因門為義故。對法云：成就眼界不成眼等故愚因者應觀於界。愚緣住處者，十二處門據增上緣境界緣門生識故。愚緣者應觀於處。

In explaining the first phrase, regarding 'if deluded about their cause, skill in the stages and fruits': the gate of the eighteen realms properly takes the seeds of the eighteen realms, as the gate of cause constitutes its meaning. The Abhidharma[-samuccaya] states: 'Possessing the eye realm while not achieving the eye, and so forth; therefore, one deluded about cause should contemplate the realms.' Regarding 'deluded about the abiding place of conditions': the gate of the twelve sense-bases is based on the gate of sovereign conditions and objective conditions generating consciousness; therefore, one deluded about conditions should contemplate the sense-bases.
