It frames foundational purificatory duties—śrāddha, disciplined Vedic study, and pañca-yajñas—that refine the pashu (individual soul) and make it fit for Shiva-puja, aligning action (karma) with devotion to Pati (Shiva).
Indirectly: Shiva-tattva is approached through purity and right conduct; these rites reduce pasha (bondage) created by neglect of dharma and prepare the seeker for Shaiva grace, where Pati is the ultimate purifier beyond ritual.
Ritual discipline is emphasized: Nāndī-śrāddha and the pañca-yajñas (five daily great offerings). These support inner steadiness needed for Shaiva sadhana, including Pashupata-oriented purification through regulated conduct.
