आधाराधेयनियमः स चैकत्वेऽपि विद्यते ।
द्रव्येष्विव हि तज्जातिकर्मस्वेव च कर्मता ॥ ८४१ ॥ādhārādheyaniyamaḥ sa caikatve’pi vidyate |
dravyeṣviva hi tajjātikarmasveva ca karmatā || 841 ||“Even though inherence is one, the restriction of container and contained is always there; by virtue of which the universal ‘substance’ is present in substances only, and the universal ‘action’ is present in actions only.”—(841)
Kamalaśīla
In the following Texts (841-845), the author sets forth the answer given by Praśastamati:—[see verse 841 above]
Praśastamati has argued as follows:—“Though Inherence is one, yet there is no likelihood of an admixture among the five Categories; because there is always a restriction as to what is contained in what; that is to say, the Universal ‘Substance’ is contained in Substances only, the Universal ‘Quality’ is contained in Qualities only, the Universal ‘Action’ is contained in Actions only; and so on, the notion of the Universals ‘Substance’ and the rest appear as restricted to a particular substratum only.”—(841)
