瑜伽論記 10.597

10.597

言若於是等者，舊人云：若於是義者，是自今善。於是善根者，依境所修同事體，下云：若等者，成上自分修義。若增者，成上勝進分修義。今釋：汎論能化與所化有情若等若勝方成能化，若劣捨彼不名能化，故言或等增也。

Regarding 'if toward these, etc.': the ancients said, 'If toward this purpose' refers to one's own present goodness. 'Toward these roots of virtue' refers to the essence of sharing common tasks cultivated based on the object. Below, 'if equal' accomplishes the meaning of cultivating one's own portion above. 'If superior' accomplishes the meaning of cultivating the portion of superior progress above. The present interpretation is: speaking generally, the converting agent and the converted sentient beings must be equal or superior to constitute an agent of conversion; if inferior, one abandons them and is not called an agent of conversion. Therefore, it says 'either equal or superior.'"
