The ten radical topics
Ancient Ṣimānanda SanskritTats_16
[Base sūtra:] The ten radical topics (mūlikārthas).
Tats_16.c1
[Verse:] Existence [of prakṛti], oneness, purposefulness, being-for-another's-sake, otherness, non-agency [of puruṣa], conjunction, disjunction, the plurality of {{puruṣa|Selves}}, and the persistence of the body [as] residual operation (śeṣavṛtti)—[these are the ten].
Tats_16.c2
[Verse:] This is the enumeration of the ten radical topics. From the [composite's] being-for-another's-sake, the existence of {{puruṣa|the Self}} is established [as] the cause of the difference of transformation. "The unmanifest exists, [it is] infinite, one"—and being-for-another's-sake, [discerned] through the nature of love and despair [in beings] and [through their] manifold ruin, [establishes purposefulness]; likewise the establishment of [puruṣa's] otherness from the three-constituent [prakṛti].
Tats_16.c3
[Verse:] From the inversion [of agency onto prakṛti follows] the non-agency [of puruṣa]; conjunction [is] for the sake of the puruṣa's seeing; and when the dissolution of the body has been attained, [disjunction follows] from the perception that [prakṛti's] purpose has been accomplished.
Tats_16.c4
[Verse:] From the difference [in beings] of [everything] from birth down to the organs, they [i.e. the puruṣas] are remembered as many. The residual operation [of the body, persisting] like the spinning of a [potter's] wheel [after the impulse has ceased]—[thus] the ten radical topics are established.
Tats_16.c5
[Verse:] These fifty notions [the contentments, attainments, etc.] were taught before by the [Sāṃkhya]saptati. But with the ten [radical topics and the] sixty categories, [the system] is called the "Ṣaṣṭitantra" (the Sixty-Topic Treatise).
