親教軌範尊似尊等者，和上名親教師，闍梨名軌範師，大同學及有德人名尊，是此下類名似尊。

Regarding 'preceptor, master of conduct, venerable one, semblance of a venerable one, etc.': the upādhyāya is called the preceptor; the ācārya is called the master of conduct; senior fellow students and virtuous persons are called venerable ones; those of an inferior class to these are called semblances of venerable ones.
