देवदारुवनौकसां प्रति ब्रह्मोपदेशः—लिङ्गलक्षण-प्रतिष्ठा-विधिः, शिवमायारूपदर्शनं, स्तुतिः
वर्तुलं चतुरस्रं वा षडस्रं वा त्रिरस्रकम् समन्तान्निर्व्रणं शुभ्रं लक्षणैस्तत् सुलक्षितम्
vartulaṃ caturasraṃ vā ṣaḍasraṃ vā trirasrakam samantānnirvraṇaṃ śubhraṃ lakṣaṇaistat sulakṣitam
قد يكون شيفا-لينغا دائريًّا أو مربّعًا أو سداسيًّا أو مثلّثًا؛ وينبغي أن يكون خاليًا من العيوب من كل جانب، طاهرًا ناصعًا. فإذا اتّصف بهذه العلامات المباركة قيل إنه حسنُ السِّمات للعبادة—جديرٌ بأن يقترب paśu (النفس المقيّدة) بخشوعٍ من Pati (شيفا)، الربّ.
Suta Goswami (narrating Linga-lakshana within the Purva-Bhaga discourse to the sages of Naimisharanya)
It gives core selection-criteria for a worship-worthy Shiva-Linga: acceptable canonical shapes and the requirement of being blemishless and pure, emphasizing ritual fitness and auspiciousness.
By allowing multiple geometrical forms while insisting on purity and flawlessness, it implies Shiva-tattva is not confined to one outward form; the paśu approaches the formless Pati through a sanctified, well-marked symbol.
It highlights puja-vidhi through linga-parīkṣā (examining the Linga’s marks): choosing a clean, unblemished form as the foundation for disciplined worship that supports Pāśupata-oriented purification.
