瑜伽師地論略纂 11.123

11.123

論解自性靜慮中云「或奢摩他品，或毘鉢舍那品」者，此云何故言毘鉢舍那耶？景師云：沈舉也，意取奢摩他。又義云：此中不然。今此中皆有品言，若在定品時，同時中非無有慧餘心、心法等，若在觀品時，非無定餘心、心等，但以隨增說為定品、觀品，據實當時恒定慧等。其句既爾，俱句、俱非亦然。

In the treatise's explanation of the intrinsic nature of dhyāna, where it says "either of the category of śamatha, or of the category of vipaśyanā," why does it mention vipaśyanā here? Master Jing says: It refers to depression and exaltation, and the intended meaning is śamatha. Another interpretation says: That is not so here. In this context, both terms include the word "category." When one is in the category of absorption, at that same time it is not without prajñā and the other minds and mental factors; when one is in the category of insight, it is not without absorption and the other minds and mental factors. It is merely spoken of as the category of absorption or the category of insight according to which is predominant, while in fact absorption and prajñā are constantly equal at that time. Since that proposition is so, the proposition of both, and the proposition of neither, are also like this.
