तमो ऽन्ते च तमःपारे चाष्टमूर्तिर्व्यवस्थितः अस्यात्मनो महेशस्य महादेवस्य धीमतः
tamo 'nte ca tamaḥpāre cāṣṭamūrtirvyavasthitaḥ asyātmano maheśasya mahādevasya dhīmataḥ
En el confín de la oscuridad, y aun más allá de esa oscuridad, queda establecido el Aspecto Óctuple (Aṣṭamūrti), propio del mismo Ser de Maheśa, el sabio Mahādeva. Él es el Pati (Señor) que trasciende la tiniebla veladora que ata al paśu (alma).
Suta Goswami (narrating the Linga Purana teaching to the sages of Naimisharanya)
It frames Mahādeva as transcending tamas (spiritual darkness) while still manifesting as the Aṣṭamūrti for the world—supporting Linga worship as a means for the paśu to move beyond pāśa (bondage) toward the Pati.
Shiva is presented as the Self of all, established beyond the reach of darkness/ignorance, yet capable of being apprehended through his eightfold cosmic manifestation—immanent and transcendent at once.
The takeaway is Pāśupata-oriented inner practice: overcoming tamas through śiva-smaraṇa (remembrance), mantra and contemplative absorption on the Lord as both beyond guṇas and present as the Aṣṭamūrti.
