Time-Reckoning (Kāla-gaṇanā): Yugas, Manvantaras, Kalpas, and Prākṛta Pralaya
तस्यान्ते सर्वतत्त्वानां स्वहेतौ प्रकृतौ लयः / तेनायं प्रोच्यते सद्भिः प्राकृतः प्रतिसंचरः
tasyānte sarvatattvānāṃ svahetau prakṛtau layaḥ / tenāyaṃ procyate sadbhiḥ prākṛtaḥ pratisaṃcaraḥ
في نهايةِ ذلك الدور تنحلُّ جميعُ مبادئِ الوجود (التَتْتْفَات) عائدةً إلى علتِها الخاصة، أي إلى بْرَكْرِتي (Prakṛti). لذلك يسمّي الحكماءُ هذا المسار «برَاكْرِتَ بْرَتِسَمْچَارَ»؛ أي الرجوعَ (والانحلال) في الطبيعةِ الأولى.

By describing the dissolution of all tattvas into Prakṛti, the verse implies that the changing cosmos is reversible and contingent; the Atman/Supreme is understood (in the Purāṇic-Yogic view) as distinct from these dissolving categories—witnessing and transcendent to material involution.
This verse is doctrinal rather than procedural: it supports Yoga-viveka (discriminative insight) by mapping how the tattvas resolve back into their cause. Such cosmological discernment is used in meditation to detach from evolutes (body-mind-world) and turn awareness toward the unchanging spiritual principle.
Indirectly: it frames dissolution in a shared metaphysical language (tattvas, Prakṛti, laya) that both Śaiva and Vaiṣṇava traditions employ. The Kurma Purāṇa often uses this common Yoga-Sāṃkhya framework to harmonize sectarian viewpoints under one cosmic order.
