ईशानकल्पवृत्तान्तः तथा लैङ्गपुराणस्य संक्षेप-सूची
सवनं ब्रह्मणश्चैव युगकल्पश् च तस्य तु दिव्यं च मानुषं वर्षम् आर्षं वै ध्रौव्यमेव च
savanaṃ brahmaṇaścaiva yugakalpaś ca tasya tu divyaṃ ca mānuṣaṃ varṣam ārṣaṃ vai dhrauvyameva ca
“These are the measures of time: the savana (ritual day-measure), the day of Brahmā, and for him the yuga and the kalpa; likewise the divine year, the human year, the ṛṣi-year, and also the Dhruva (sidereal) reckoning.”
Suta Goswami
It frames Linga-oriented sādhanā within a precise Shaiva cosmology: worship and vows gain meaning when aligned to kāla (time), from savana-based ritual timing up to kalpa-scale cycles in which the Linga manifests and is re-established.
By cataloging time-measures up to Brahmā’s kalpa, it implies Shiva as Pati beyond these measures—Time is a created order, while Shiva-tattva is the transcendent ground in which creation appears and dissolves.
The mention of savana points to Vedic-aligned ritual scheduling (daily rites and observances). In Shaiva usage, it supports disciplined timing for pūjā, japa, and vrata—preparatory structure for Pāśupata-style sādhanā.
