成唯識論述記 2.803

2.803

述曰：於中有四：一、標宗；二、釋難；三、引證；四、立理。此即標宗，一切有漏、無漏種子，皆法爾有，非是本無，今從熏生。

The Commentary states: Herein there are four parts: 1. stating the thesis; 2. resolving objections; 3. citing scriptural proof; 4. establishing the reasoning. This is stating the thesis: all contaminated and uncontaminated seeds exist naturally; they are not originally non-existent and now born of perfuming.
