唯識二十論述記 2.39

2.39

述曰：自下廣釋極微不成。於中有三：初問不成；次答不成；後申正義，總結不成。此即初問，外人既見非其極微一實不成，有隨一過。遂問論主：云何不成？

Commentary: Below is a detailed explanation of why atoms are untenable. In this there are three parts: first, questioning the untenability; second, answering the untenability; third, stating the correct doctrine and concluding its untenability. This is the first, the question: the opponent, seeing that his atom being a single substance is rejected as untenable, incurring the fault of an unaccepted reason (asiddha), thereupon asks the treatise master: 'Why is it untenable?'
