अक्रोधो गुरुशुश्रूषा शौचमाहारलाघवम् नित्यं स्वाध्याय इत्येते नियमाः परिकीर्तिताः
akrodho guruśuśrūṣā śaucamāhāralāghavam nityaṃ svādhyāya ityete niyamāḥ parikīrtitāḥ
Freedom from anger, devoted service to the Guru, purity, lightness in food, and daily svādhyāya (sacred study)—these are proclaimed as the niyamas for the Śaiva practitioner; by them the bound paśu becomes fit for the grace of Pati.
Suta Goswami (narrating Shaiva disciplines to the sages of Naimisharanya)
It defines the inner disciplines (niyamas) that make Linga-puja effective—purity, restraint, and Guru-centered practice refine the paśu so worship becomes a vessel for Shiva’s anugraha (grace).
By implying Shiva as Pati, the liberating Lord: when anger and impurity (forms of pāśa) are reduced through niyama, the soul becomes receptive to Shiva-tattva as grace and illumination rather than mere ritual form.
A Pashupata-oriented niyama set: guru-śuśrūṣā (lineage discipline), śauca (purificatory conduct), āhāra-lāghava (dietary regulation), and nitya-svādhyāya (daily mantra/scriptural recitation) as the foundation for sadhana.
