Adhyaya 4: अहोरात्र-युग-मन्वन्तर-कल्पमान तथा प्रलयान्ते सृष्ट्युपक्रमः
अंशकः षट्शतं तस्मात् कृतसंध्यांशकं विना त्रिद्व्येकसाहस्रमितो विना संध्यांशकेन तु
aṃśakaḥ ṣaṭśataṃ tasmāt kṛtasaṃdhyāṃśakaṃ vinā tridvyekasāhasramito vinā saṃdhyāṃśakena tu
因此,aṃśaka 的数目为六百;若除去分配给克利多劫(Kṛta-yuga)暮光 saṃdhyā 的那一份 aṃśaka,则其度量为三千——再者,亦不计入 saṃdhyā-aṃśaka。
Suta Goswami (narrating Purāṇic cosmology to the sages of Naimiṣāraṇya)
It frames sacred time in precise units (aṃśakas and yuga-sandhyās), supporting the Shaiva idea that worship of the Linga is most efficacious when aligned with cosmic junctions (saṃdhyā), where Pāśa loosens and the Pashu turns toward Pati.
By treating time-measurement as a revealed, orderly principle within creation, it implies Kāla as a Shakti of Pati (Śiva), under whose governance the yugas and their transitions unfold—Śiva-tattva as the transcendent regulator beyond changing measures.
The emphasis on saṃdhyā points to sandhyā-kāla discipline—regular twilight worship, japa, and inner recollection—used in Shaiva sādhanā to stabilize the mind and orient the Pashu toward liberation under Pati.
