 Hence for the Sarvāstivādin, conventional reality (samvṛtisatya), composite-existence (avayavi-dravya / rdzas grub), and the lack of intrinsic reality (niḥsvabhāva) are all equivalents. A conventional reality is therefore characterised as a reducible conventional entity on three grounds: (i) conventional reality is both physically and logically reducible, as it disintegrates when it is subjected to physical destruction and disappears from our minds when its parts are separated from it by logical analysis; (ii) conventional reality borrows its identity from other things including its parts, concepts etc., it does not exist independently in virtue of its intrinsic reality (niḥsvabhāva), the exclusion of its parts and concepts thus affects and reduces its inherent nature; and (iii) conventional reality is a product of mental constructions, like that of conventionally real wholes, causation, continuum etc, and it does not exists intrinsically.
