從生眼等根，三和前六處者，此是鉢羅奢佉，此位通多念也。從名色後三和已前生眼等根，此位五蘊說名六處，六處創圓，根相顯故，但標六處。

"From the arising of faculties like the eyes, / prior to the threefold gathering, is the six sense spheres": this is the praśākhā, and this stage extends over many moments. After name-and-form and before the threefold gathering, the faculties such as the eyes arise; the five skandhas of this stage are called the six sense spheres. Because the six sense spheres are newly rounded out and the features of the faculties are prominent, they are simply designated as the six sense spheres.
