Shiva Purana — Vayaviya Samhita, Shloka 28
Śiva’s Freedom from Bondage and His Cosmic Support (शिवस्य अबन्धत्वं तथा सर्वाधिष्ठानत्वम्)
अकारश्च महाबीजं रजः स्रष्टा चतुर्मुखः । उकारः प्रकृतिर्योनिः सत्त्वं पालयिता हरिः
akāraśca mahābījaṃ rajaḥ sraṣṭā caturmukhaḥ | ukāraḥ prakṛtiryoniḥ sattvaṃ pālayitā hariḥ
“A”是大种子（mahābīja），是罗阇斯之德，也是四面造物主梵天（Brahmā）。“U”是自性（Prakṛti），是胎藏（yoni），是萨埵之德，也是护持者哈利（Hari，毗湿奴）。

FAQs
It maps the seed-sounds of sacred vibration to cosmic functions and guṇas—showing how creation and preservation arise within Prakṛti through rajas and sattva, while Shaiva teaching ultimately points beyond guṇas to Pati (Shiva) for liberation.
In Linga worship, the devotee contemplates the whole cosmos—Brahmā, Viṣṇu, and the guṇas—as dependent powers, while the Linga signifies Shiva as the transcendent Lord (Pati) who governs them and grants grace beyond Prakṛti.
Meditate on the sounds ‘A’ and ‘U’ as parts of AUM, reflecting on rajas and sattva as movements of Prakṛti; then stabilize the mind in mantra-japa (especially Shiva-mantra) to transcend guṇas through devotion and inner stillness.
