स्थिरलिंगश्न यन्नित्यं तस्मात् स्थाणुरिति स्मृत: । ये ऊर्ध्वभागमें स्थित होकर देहधारियोंके प्राणोंका नाश करते हैं। सदा स्थिर रहते हैं और जिनका लिंग-विग्रह सदा स्थिर रहता है। इसलिये ये 'स्थाणु” कहलाते हैं

Vāyu said: “Because his emblem (liṅga) remains ever unmoving and fixed, he is therefore remembered by the name ‘Sthāṇu’—the Steadfast One.”
वायुदेव उवाच
The verse explains an epithet of Śiva—‘Sthāṇu’—grounded in the idea of unwavering steadiness: the divine emblem (liṅga) is described as perpetually fixed, symbolizing immovability and constancy.
Vāyudeva is speaking and provides a traditional derivation/justification for the name ‘Sthāṇu,’ characterizing the deity through the quality of being ever-stable and unmoving.
