Vaṃśānuvārṇana and the Transition to the Fourth (Upasaṃhāra) Pada
नैमित्तिकः प्राकृतिको यश्चैवात्यन्तिकोर्ऽथतः / त्रिविधिः सर्वभूतानामित्येष प्रतिसंचरः
naimittikaḥ prākṛtiko yaścaivātyantikor'thataḥ / trividhiḥ sarvabhūtānāmityeṣa pratisaṃcaraḥ
The Naimittika, the Prākṛtika, and the Ātyantika—thus, in essence, are three; this is the threefold reabsorption (pratisaṃcāra) of all beings.
