EXPLANATORY NOTES
Ācārya Umasvami's Tattvārthasūtra
धर्माधर्मयोः कृत्स्ने ॥
(5-13)
The media of motion and rest pervade the entire universespace.
Ācārya Pujyapada’s Sarvārthasiddhi The word 'entire' indicates all-pervasiveness. The media of motion and rest are not situated in the universe like a pitcher in a house. These two pervade the entire universe (without leaving any inter-space) in the manner of oil in the sesamum seeds. And these two interpenetrate without any obstruction, as these are possessed of the capacity of immersion2.
The material objects having form are different from the non-material substances such as the medium of motion. These extend from one unit of space to numerable, innumerable and infinite units of space. What is the nature of accommodation of material objects?
