देवदारुवनौकसां प्रति ब्रह्मोपदेशः—लिङ्गलक्षण-प्रतिष्ठा-विधिः, शिवमायारूपदर्शनं, स्तुतिः
अङ्गुष्ठमात्रं सुशुभं सुवृत्तं सर्वसंमतम् समनाभं तथाष्टास्रं षोडशास्रम् अथापि वा
aṅguṣṭhamātraṃ suśubhaṃ suvṛttaṃ sarvasaṃmatam samanābhaṃ tathāṣṭāsraṃ ṣoḍaśāsram athāpi vā
A Śiva-liṅga may be made the size of a thumb—beautiful and well-rounded, approved by all. It should be proportionate with a central navel-like mark, and it may be fashioned with eight edges, or even with sixteen edges.
Suta Goswami (narrating Shiva-puja and linga-construction injunctions to the sages of Naimisharanya)
It standardizes acceptable measurements and geometries for the Śiva-liṅga, showing that even a small, thumb-sized liṅga is ritually complete and universally sanctioned for worship.
By allowing multiple forms (round, eight- or sixteen-faceted) while insisting on auspicious proportion, it points to Śiva as Pati—one reality approachable through varied, regulated symbols without changing the underlying tattva.
It emphasizes puja-vidhi through correct iconometry (liṅga-lakṣaṇa); in Pāśupata terms, disciplined external worship supports the pashu’s purification from pāśa and steadies meditation on Pati.
