Sarvadarshanasangraha 13.67

13.67

since in the chapter on action (Kriyāsamuddeśa) action is established as having the nature of a universal, the meaning of a verbal root is indeed Being. Because the affixes -tva, -tal, and so forth are prescribed in the sense of being by [the rule] "tasya bhāvas tvatalau" (Pāṇini 5.1.119), it is appropriate that they designate Being. And that Being is eternal because it lacks origination and destruction. Because the entire phenomenal world is its illusory transformation (vivarta), and because it is devoid of limitation by space, time, and entity, that Being is designated as the great Self—this is the meaning of the two verses.
