Kālajñāna (Knowledge of Time) and Mṛtyu-cihna (Signs of Death): Śiva’s Instruction to Umā
एतत्प्रमाणं विज्ञेयं वामवायुप्रमाणतः । सव्येतरे दिनान्येव चत्वारश्चानुपूर्वशः
etatpramāṇaṃ vijñeyaṃ vāmavāyupramāṇataḥ | savyetare dinānyeva catvāraścānupūrvaśaḥ
இந்த அளவை வாமவாயுவின் அளவுகோலின்படி அறிய வேண்டும். வலப்புறமும் மற்ற (இடப்புற) பக்கமும் நாட்கள் முறையே நான்கு நான்காக அமையும்।

Tattva Level: pashu
Shiva Form: Dakṣiṇāmūrti
Role: teaching
It frames spiritual discipline in measurable, ordered practice: regulating life-force (vāyu/prāṇa) in a sequence, so the bound soul (paśu) can be steadied and oriented toward Pati (Śiva) for liberation.
Breath-regulation supports one-pointedness (ekāgratā) needed for Linga-worship and mantra-japa; by stabilizing prāṇa, devotion becomes steady and the mind rests in Śiva’s presence in saguna upāsanā.
A yogic method of observing/standardizing practice by the left-channel breath (iḍā/vāma-vāyu) and following a fixed sequence of days or cycles—useful as a framework for regular japa, dhyāna, and vrata observances.
