Kālajñāna (Knowledge of Time) and Mṛtyu-cihna (Signs of Death): Śiva’s Instruction to Umā
नाडी यदा च वहति त्रयोदशदिनावधि । सम्वत्सरं भवेत्तस्य चतुर्मासाः प्रकीर्तिताः
nāḍī yadā ca vahati trayodaśadināvadhi | samvatsaraṃ bhavettasya caturmāsāḥ prakīrtitāḥ
When the nāḍī-current flows for a span of thirteen days, that is called a “year” for it; and its four months (cāturmāsya) are thus spoken of.

Tattva Level: pashu

It reframes ‘time’ through the inner movement of prāṇa in the nāḍīs, pointing to yogic discipline where spiritual progress is measured by inner purification and regulation rather than only external calendars—supporting the Shaiva aim of steady approach to Pati (Shiva) through inner practice.
In Shaiva practice, Saguna worship (Linga-pūjā, mantra, and devotion) stabilizes the mind, and that steadiness supports prāṇa regulation; the verse highlights the subtle, inner ‘rhythm’ that matures alongside outer worship, leading the devotee toward Shiva’s grace and liberation.
A yogic focus on observing and regulating prāṇa-flow (nāḍī-vāha) through disciplined japa of the Panchakshara (Om Namaḥ Śivāya) and breath-awareness; it implies measured, consistent sādhana aligned with inner cycles rather than mere external timing.
