शुद्धस्य सिद्धयो दृष्टा नैवाशुद्धस्य सिद्धयः न्यायेनागतया वृत्त्या संतुष्टो यस्तु सुव्रतः
śuddhasya siddhayo dṛṣṭā naivāśuddhasya siddhayaḥ nyāyenāgatayā vṛttyā saṃtuṣṭo yastu suvrataḥ
诸悉地唯于清净者显现;不净之人,悉地终不生起。然具善誓之行者,安住于以正法所得之生计而知足者,便堪入湿婆之道,使被缚之灵魂(paśu)趋向主宰(Pati,湿婆)。
Suta Goswami (narrating the teaching on right conduct within the Linga Purana discourse)
It frames Linga-upasana as grounded in śauca (purity) and nyāya (righteous living); without inner and outer purity, ritual and mantra do not mature into genuine spiritual fruit.
By implication, Shiva (Pati) is approached through purification of the paśu (individual soul) from pāśa (bondage) such as impurity and unrighteous conduct; siddhi is a byproduct of alignment with that Shaiva order.
Pashupata-oriented discipline: śauca (purity), santoṣa (contentment), and nyāya-vṛtti (righteous livelihood) as foundational observances that stabilize mantra-japa and Linga-puja.
