वासिष्ठकथनम् (आदित्य–सोमवंशवर्णनम् तथा रुद्रसहस्रनाम-प्रशंसा)
कला काष्ठा लवो मात्रा मुहूर्तो ऽहः क्षपा क्षणः विश्वक्षेत्रप्रदो बीजं लिङ्गमाद्यस्तु निर्मुखः
kalā kāṣṭhā lavo mātrā muhūrto 'haḥ kṣapā kṣaṇaḥ viśvakṣetraprado bījaṃ liṅgamādyastu nirmukhaḥ
هو الزمانُ نفسُه—كلا (kalā) وكاشتها (kāṣṭhā) ولافا (lava) وماترا (mātrā) وموهورتا (muhūrta)، والنهارُ والليلُ واللحظة. يمنحُ حقلَ الكون (viśva-kṣetra) وهو البذرة (bīja): اللِّينغا الأوّل، الأزليّ بلا بداية، بلا وجهٍ ظاهر، المتعالي عن كلِّ صورةٍ محدودة.
Suta Goswami (narrating the Linga Purana to the sages of Naimisharanya)
It frames the Linga as the primordial causal seed (bīja) and the very principle of Time, so Linga-pūjā becomes worship of the source that measures and sustains all cosmic processes.
Shiva is shown as Pati beyond limiting form—“nirmukha” (faceless)—yet immanent as Kāla, the inner regulator of day, night, and every instant, and as the giver of the universe-field (kṣetra).
The takeaway is contemplative Linga-upāsanā: meditate on the Linga as Kāla and bīja, loosening pāśa (bondage) by seeing all moments and experiences as arising within Shiva’s kṣetra.
